The 8 Best Zip Line Kits
Updated by · How we research
Eight backyard zip line kits compared on cable, brake, trolley and rider limit. The Hyponix 100-Foot leads for its long brake and backup cable. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki.
In July 2026, federal regulators recalled about 60,000 backyard zip line kits after cables, turnbuckles and seats broke and their spring brakes proved too soft to stop riders. That makes the hardware and the brake more important than cable length. These kits suit families with two sturdy trees, a gentle slope and the patience to inspect every part before each ride.
Editor's Notes
October 23, 2026, by Ezvid Wiki Admin:
The Hyponix 100-Foot takes the top spot because it pairs a long spring brake with a backup cable at the turnbuckle, two details that matter more than length on a backyard line. The old list needed more than a reshuffle. Its TRSmima LSTZ1 is gone, because Trsmima kits and spring brakes were recalled this summer after cables and seats broke and riders were hurt. The ZLP Manufacturing Ultimate Torpedo, Zip Line Gear Rogue, Sleadd 250 LX, American Ninja Warrior Ninjaline, Slackers Night Riderz and Adventure Parks ZL35 are no longer available.
The CTSC ZK2409 stays, though it now sits lower and suits kids and smaller adults best. New picks include the Zip Line Gear Chetco for sturdier hardware, the Fologtoo 150-Foot for longer yards and the Xben 98-Foot for a tight budget.
The most useful evidence for this category came from federal recall notices, which spell out exactly how cheap kits fail, along with the Hyponix manual and Zip Line Gear's guide to choosing anchors.

It wound up being a busy round of updates, with a variety of availability issues leading to the elimination of the Alien Flier X3-H100 and Slackers Hawk Series. We were especially disappointed to see the Hawk Series go, as many users appreciate its build quality, but believe that fans of the company will still be well served by our remaining inclusion, the luminescent Slackers Night Riderz. We also swapped out the Sleadd 150 LX for the Sleadd 250 LX, as the latter didn’t cost much more than the former, and we liked that it was longer and came with a harness.
The ZLP Manufacturing Ultimate Torpedo joined the Zip Line Gear Rogue as one of the only options on our list that’s offered in lengths up to 500 feet. Both options boast a 350-pound capacity, and both are notably expensive choices, but the Ultimate Torpedo is more affordable than the Rogue, and thus earned a higher spot on our list.
Contrastingly, the Trsmima LSTZ1 became one of the shortest options we ranked, with a total length of 98 feet. Its 1/4-inch cable is slimmer than other options, but thanks to its 304 stainless steel construction it can hold up an impressive 450 pounds, which is the primary reason it ranked so high on our list, but its patented spring brake and 10-year limited warranty didn’t hurt its cause, either.
Our last new addition was the American Ninja Warrior Ninjaline, which has a modest 200-pound capacity and a relatively short length of 90 feet. Despite its admitted mediocrity, it has been reviewing well and it is priced reasonably, so we thought it was worth including for fans of the show (or, more likely, parents of fans of the show) who might like to implement it as part of their own backyard obstacle course.
On the other hand, if your kids aren’t quite of a zip-lining age yet, but you’d still like to find ways to encourage active backyard recreation, then maybe consider getting started with a small play structure or dome climber.

All the choices on this list were evaluated for their safety features, but none of them will be safe unless they are installed and used exactly as the manufacturer recommends. For those who aren't very handy, safety experts recommend having them professionally installed.
While the Zip Line Gear Rogue is a lot pricier than most you do get what you pay for. We put it in the top spot because its components are heftier than those generally sold for home usage, with 5/16 steel cable instead of the usual 3/16, plus the dual wheel bearing trolley will stand up to frequent usage for years. For those with the space, this option is great if it's often going to be used by adults as well as children.
The Slackers Night Riderz takes a top spot because the brand for all of its ziplines provides quality installation hardware, like locking nuts and bolts, a turnbuckle safety backup, plus protective tubing for section of cable that wraps around your tree. We chose the brand's Night Riderz kit because it provides a 100 feet of cable, and their upgraded compression braking system.
Special Honors
Zip Line Gear Rogue Kits For long or heavily used backyard lines, Zip Line Gear's Rogue kits step up to thicker cable and add a bungee brake, a tensioner and a tree saver. The company also sells trolleys, seats, harnesses and brakes on their own, so a budget kit can be upgraded part by part. ziplinegear.com
Tree House Supplies This treehouse hardware company sells zip line kits and parts alongside its treehouse gear, and its zip line guide explains when a fixed trolley is enough and when a removable one makes more sense. treehousesupplies.com
Brakes, Stop Blocks And What The Recalls Show
Most budget kits use a spring brake, a long steel coil that slides on the cable and compresses when the trolley hits it.
A stop block and a brake do different jobs. The stop block is a fixed point near the end of the cable that the trolley can't pass. The brake slows the rider before the trolley gets there. Most budget kits use a spring brake, a long steel coil that slides on the cable and compresses when the trolley hits it. A longer spring spreads the stop over more distance, which is gentler, and heavier or faster riders need more of it. Pro-style kits often skip the spring and add a bungee brake, which Zip Line Gear sells for its Chetco and Rogue kits.
The recalls show where cheap kits fail. In July 2026 the U.S. Consumer Product Safety Commission announced a recall of about 60,720 Trsmima kits and 19,120 spring brakes: cables, turnbuckles and seats could break or come apart, and the brakes were too soft to stop riders, with 20 injuries reported (CPSC). A 2024 recall covered Jugader kits whose cable could snap (CPSC), and a 2016 recall covered BYA Sports Skyline kits with crimps that could fail (CPSC). None of those kits is on this list. Whatever you buy, check the cable for rust and broken strands, the clamps for slipping and the brake for wear before each session.
Trees, Anchors, Slope And Tension
Zip Line Gear's anchor guide says the attach point on a tree should be at least 12 inches thick on a healthy tree, and that anchors can see loads of roughly 800 to 3,000 pounds once a rider is on the line. Wrap each trunk with a tree saver or padded strap so the cable doesn't cut into the bark. If you lack two good trees, you'll need posts or a platform, which can cost more than the kit.
An installation guide from The Yard Masters recommends wrapping the cable around the anchor several times, using two clamps about 6 inches apart, tightening gradually and running a weighted test before anyone rides. It suggests a slope of about 5 to 8 degrees, a landing end lower than the start and a cleared run-out past the brake. Leave some sag in the middle: a piano-tight cable puts more load on the trees and hardware. The same guide recommends a monthly inspection with a written log.
Trolleys, Harnesses And Helmets
The trolley is the pulley that rides the cable. A fixed trolley stays on the line, and Tree House Supplies says that type works well on lines up to about 200 feet; a removable trolley clips on and off so it can come down between rides. Look for sealed ball bearings and a handle that keeps fingers away from the cable.
Most kits ship with a disc or wooden seat. A seat is fine for kids who can hold on, but a seat belt or harness clipped to the trolley keeps a rider attached if they let go. A climbing-style sit harness is the safer choice for adults and longer lines, and a bike or climbing helmet is cheap insurance. ASTM F2959, the U.S. standard for commercial aerial adventure courses, doesn't apply to home kits, and a CE or RoHS mark on a box is not a zip line safety rating. Keep one rider on the line at a time, supervise children, and check with your town and your homeowner's insurer before building.
How we researched this
We compared about 20 backyard zip line kits, read the Hyponix manual and Zip Line Gear's guides to its kits and to anchors, looked for patterns in owner feedback on every pick, and checked each brand against U.S. Consumer Product Safety Commission recalls. That search turned up the 2026 Trsmima recall and earlier recalls of Jugader and BYA Sports kits. We found no independent lab tests of backyard zip line kits.

Frequently asked questions
How long should a backyard zip line be?
Most backyard kits run from about 60 to 200 feet, and 100 to 150 feet suits a typical yard with two good trees. Measure the gap between anchors and add extra cable for wrapping the trees. Longer lines need a longer brake and more slope control.
What does it cost to install a zip line?
The kit is the main cost. Budget extra for a bungee brake if the kit lacks one, a harness and helmet, tree savers, and posts or a platform if you don't have two sturdy trees. Plan on replacing clamps, cable or brake parts as they wear.
Are backyard zip lines safe?
They can be, with sound anchors, a working brake, a harness or seat belt, a helmet and adult supervision. The 2026 Trsmima recall showed what happens when cables, turnbuckles and brakes are weak, so inspect every part before each session and stop using any kit with rust, frayed strands or slipping clamps.
Do I need a harness for a zip line?
Young kids on a short, low line can ride a seat, but a seat belt or sit harness clipped to the trolley keeps a rider on if they let go. For adults and longer lines, a climbing-style harness and a helmet are the safer choice.
Can I attach a zip line to trees?
Yes, if the trees are healthy and at least 12 inches thick at the attach point, per Zip Line Gear's anchor guide. Use tree savers or padded straps so the cable doesn't cut the bark, and check the trees each season for damage or rot.
What slope does a zip line need?
The landing end should sit lower than the start, with a gentle sag in the middle rather than a tight cable. One installation guide suggests about 5 to 8 degrees of slope. Run a weighted test before the first ride and adjust the tension if the trolley stops short or hits the brake hard.
