Griplock® Grippers are sophisticated in design but simple to use to hang your pictures or fine art. Here’s how it works:
Insert the cable into the plunger and slide the gripper to the desired position. Where it stops it locks®
To re-adjust, simply depress the plunger with your fingertip and move the gripper to a new position. Release the plunger to lock.
The 3- or 6-ball gripping mechanism is spring-loaded and allows the gripper to move freely up the cable. It cannot move down unless the plunger is depressed.
While there is any weight at all on the gripper, the plunger cannot be depressed. An optional “safety nut” or “safety cap” can be added to completely lock the mechanism in both directions. The Greater The Weight, The Stronger It Grips.
Materials & Finishes
Griplock® Grippers are made of nickel-plated brass with a few exceptions. Internal mechanisms are comprised of brass and stainless steel. Type-50 and Type-80 Grippers are also available in a black zinc finish. Our Retail Display Grippers are finished in satin-chrome. Other finishes are available upon request. Griplock® Keyrings are made of anodized aluminum and come in several colors.
Most Griplock® Grippers have either internal or external threads to attach them to the object being suspended. The following chart contains thread and KO (Knock-Out) size information that may be useful, particularly to our Lighting Industry customers.
About Aircraft Cable
Aircraft Cables, also known as wire ropes, have diameters ranging from 1/32” to 1/4” and are composed of six steel strands wound around a seventh steel stranded core.
This stranded steel core adds strength and crush-resistance to the cable. Aircraft cable is classified by the number of strands in the cable multiplied by the number of wires in each strand. For example, the notation 7×7 indicates that the cable has seven strands made up of seven wires in each strand. Similarly, the notation 7×19 indicates that the cable has seven strands made up of nineteen wires in each strand. The greater the number of wires, the greater the flexibly of the cable. Griplock® Cables are 7×7 or 7×19 galvanized or stainless steel (304 or 316) medium-to-high tensile strength aircraft cable.
NOTE: Aircraft cable was developed, and is still used today, to provide a direct mechanical link between an aircraft’s controls and its crucial and hard-to-reach control functions.
Galvanized & Stainless Steel Aircraft Cable
Galvanized Aircraft Cable (also known as GAC) is composed of wires that, prior to stranding, have been zinc-plated to prevent corrosion. These cables are an effective and economical alternative to stainless steel in mild environments. Griplock®’s standard stainless steel cable is constructed of 304 Stainless Steel. 316 Stainless Steel is also available to add extra corrosion resistance, but it has lower break strength than 304 Stainless Steel cable. Both 304 Stainless Steel and Galvanized Aircraft Cable have approximately the same break strengths.
Cable Sleeves & Terminals
Sleeves and terminals (also known as stop-sleeves, stops, crimps and swages) are molded or crimped to the end of a cable, allowing the cable to be captured by a cable coupler or other non-mechanical holder which attaches the cable to a structure or fixture.
Zinc Die-Cast (ZDC) Terminals are molded to a cable end that has been “bird-caged”, allowing the molten zinc to adhere to each individual wire. This technology has proven itself in the automotive and aviation industries. Griplock® Systems offers a comprehensive range of ZDC terminals.
Swaged Terminals can be made of steel, stainless steel, aluminum or copper and come in a variety of shapes and sizes.
Both types of Griplock® terminal are guaranteed to hold the full published break weight of the cable. U.S. Wire Rope Specifications
NOTE: Griplock® Systems does not recommend field-installing swaged terminals onto cable. Griplock® Systems waives any liability for accidents resulting from field- or non-factory-installed swages and terminals.
