The Stop Block can be used to create a no-pass point on any zip line cable, such as dropping over a body of water, prohibiting riders from reaching the end of the cable or it can be used as an emergency backup to a brake system. The Stop Block is not intended for use as a stand alone primary brake; riders should have little to no momentum upon impact with the Stop Block.

Use as a stand alone emergency arrest device for gravity brake zip lines or as a secondary safety backup for a primary brake system.

Note: The Stop Block is NOT intended for use as a primary braking system. Riders should have little to no momentum when coming in contact with the block. The Stop Block is designed to grip the cable whereas the Bungee Block has a broad groove to slide freely on the cable.  The Bungee Brake Block and the Stop Block are not interchangeable.

FAQ

How do I measure elevation change in my backyard?

Please refer to the manual that comes with your kit for specific installation instructions. 

Stand at the end tree and hold a 4 FT Carpenter’s Level like a rifle.  Holding one end up to your eye, point the opposite end at the base of the starting tree, right where the dirt and tree meet. Make sure the bubble is between the two hashes indicating level (crouch down if your yard has a minimal slope or climb a ladder if your yard has lots of slope).  

Once you have the level aiming at the base of the starting tree, measure from the Carpenter’s Level down to the ground.  This measurement is your natural elevation change.

How do I figure out the slope for my zip line?

Please refer to the manual that comes with your kit for specific installation instructions.

The slope determines the speed of the zip line. Essentially this is the angle you set the cable at between the two trees. The slope is calculated by multiplying the distance between your trees times .03 or 3%.

More details on Slope can be found in the Zip Line Gear handbook included with your purchase. You can also view a digital version of the “Cable Slope & Sag” right here. We recommend finding a landscape with a natural slope of 3% to 6%, This is a 3’ - 6’ foot drop per 100’ feet. 

For zip lines that will NOT utilize a Bungee Brake System, (a Stop Block is NOT a braking system) the maximum allowable slope is 3%. For zip line setups that include a Bungee Brake, the maximum allowable slope is 6%. 

!!WARNING!! Zip line must never exceed 6% (6’ foot drop per 100’ feet) riding slope. High speed collision with end point may cause injury or death.

I don't have trees. Can I use posts?

Yes you can, but you need to carefully read the instructions for how to select, and install posts in the Backyard Zip Lines handbook included with your purchase. Alternatively, you can review the information in the digital version of our handbook right here.

If you are in any doubt as to how to properly select and install a wood post, please do not hesitate to contact us at 888-476-3701.
