Types of Hardware
GALVANIZED AIRCRAFT CABLE
We at Zip Line Gear love galvanized aircraft cable. Our Galvanized Aircraft Cable is 7x19 in construction and is ideal for virtually any zip line ride at least 5 miles from a coastal area (we suggest Stainless Steel Cable for use in salt spray applications). Available in various lengths and diameters, Galvanized Aircraft Cable is your first stop in building a backyard zip line or commercial zip line.
Because we know you will need just a little extra cable to account for zip line sag and ease of set up, we conveniently add an extra 10' of cable to each of our kits. Be sure to add it to your overall length, if you're building your own kit. You may also consider adding a Mechanical Cable Splice to the end of your custom length of cable. This swage is applied with a hydraulic press and through testing, is proven to be stronger than making the same loop with Cable Clamps.
A Cable Sling is the ideal termination for use with just about any zip line anchor. Available in various sizes, these beauties help protect your trees from harm and provide stability for your zip line. We recommend using wooden blocks, or Tree Savers, spaced underneath the cable to protect the cambium layer of the tree. Apply the Cable Sling by looping around the tree once and attaching to the main zip line cable.
Match the size of the cable sling (1/4", 5/16" and 3/8") to the size of the main zip line cable. For trees larger than 3' in diameter please call us for a custom length cable sling at 888-476-3701.
Our galvanized Eyebolts shaft length is measured from the end of the bolt to the base of the eye (i.e. the advertised length is just the shaft, excluding the eye). The threads extend halfway down the shaft. For example a 10" eyebolt has threads 5" down the shaft.
FORGED CABLE CLAMPS
Drop forged galvanized wire rope clip for 1/4", 5/16" and 3/8" aircraft cable. 3-4 clips are required for each termination. For heavy duty and commercial applications.
Thimbles are lifesavers for your zip line cable. They reduce crimping of the cable, and help maintain the integrity and strength of your cable by eliminating abrasion between the cable and your anchor point. Grab a few to help in setting up your backyard zip line.
Note: use a thimble as an insert in any sharp turns and termination points on a cable.
Staples can be used for a variety of applications. If you intend to wrap a cable directly around an anchor point, using a staple is a good way to keep the cable from moving vertically up or down. The longer 8" staples make excellent footholds when driven into a tree or pole; especially when the use of a ladder isn't a viable option.
Note: you should never use a staple in an application where the staple is a critical component (i.e. if the staple were to pull out, the entire system would be compromised).
EYE LAG SCREWS
The Eye Lag Screw is a galvanized piece of hardware useful in many different applications. An Eye Lag Screw is measured from the base of the eye to the end of the screw threads (e.g. a 4" lag screw has a shank length of 4" with the eye portion of the screw extending past this) and is available in various sizes to fit to your specific zip line needs.
Note: Not for use in life support applications.
This Eye/Jaw Swivel has a number of uses. Primarily this piece of hardware would be used as cable connecting hardware.
Quick Links are simple in name, design and function. A quick link is used as an integral connection in zip line set ups. A quick link’s size corresponds to the diameter of the objects that can pass through its mouth as well as the material thickness of the quick link itself. These carbon steel, zinc-plated connections may be used for life support systems when appropriate ratings are followed.
SCREW PIN SHACKLES
Shackles are most often used in zip line applications to terminate the end of a zip line cable to an eyebolt or cable sling. The size of the shackle corresponds to the thickness of the objects that can pass through its mouth as well as the material thickness of the shackle itself.
Snap Hooks are ideal for situations where a quick connection is needed, but is not intended for use in life support situations. The snap hook can be used for attaching a rope to the zip line trolley for retrieval.
Turnbuckles are an essential component of any zip line. Turnbuckles are primarily useful in adjusting zip line tension once your zip line is operational and the cable stretches from use. All of our Classic Kits come with either one or two turnbuckles, depending on the kit's design.
Turnbuckles allow for adjusting tension on a zip line cable at any time. Turnbuckles can also be used for tensioning guy wires.
When deciding on which Hardware to purchase for your zip line project, the main concern you will have is matching rated materials so that they are as safe as possible. On many zip lines, the hardware used for terminating and anchoring is a combination of Cable Clamps, cable Slings and Turnbuckles.
When evaluating zip line hardware you will want to look for hardware that, at a minimum, exceeds your needs. How you determine if a product exceeds your needs is to check its strength ratings and working load limits. We have a great piece written on those two terms, but they can be summed up. A strength rating is often also known as the breaking strength and is the maximum load the product can hold before breaking. Building off of that number is the safe working load limit which is typically the load at which you want to functionally use a piece of hardware over time. This limit is typically 1/5 of the breaking strength.
As always, do not use pieces of hardware in rigging a zip line if they are not capable of life support.
