Choosing The Right Wire Grips For Cable Support
Reduce Breakage, Damage and Cable Pull-Out in Vertical Cable Runs and Flexing Applications
When running cable and wiring in vertical spaces, or for connections that bend and flex, it is crucial that the right type of cable support grip is used. Relying on the connectors or terminations alone isn’t enough in these applications.
Adding a Wire Mesh Cable Support Grip is the Best Solution to Secure Cable Runs
Without proper wire support and cable strain relief, there is a greater potential for stress on the wiring.
Whether that stress occurs from the dead weight of the cable, or from flexing and bending, the results can be cause serious downtime.
Breakage of the cable, damage to it or the surrounding area and power outages are common without proper wire support.

There are many things to consider when choosing a cable or wire support grip. Here we identify the most important considerations when choosing strain relief connectors for vertical cable runs, as well as connections that bend and flex.
Consider the Application Purpose, Environmental Requirements and Flexing Demands
Each application has different requirements, which should be considered first when choosing cable support grips.
With applications ranging from residential to commercial and industrial in industries such as Electrical, HVAC, Utility, Agricultural, Automotive, Communications and more, cable support grips are as versatile as the purposes they serve.
Cable Pulling Grips provide easy pulling and placement of cable, and range from light- to heavy-duty. They are typically made of galvanized steel.
Strain Relief Grips are ideal for applications where bending, flexing or vibration require additional protection against cable pullout.
Weight Support Grips are designed to support the weight of electrical cable in vertical, horizontal or sloping positions. They permit the cable to expand and contract, without losing gripping ability.
In addition, it is also important to consider if the application requires permanent support or is a temporary solution.
Different cable support grips can be used in different environments, from dry, indoor areas to wet outdoor environments or even highly-corrosive ones.
When considering environmental impacts, the materials of the wire support grip may become a factor.
Standard materials will handle light-duty applications, but if the application requires corrosion-resistance, then a material upgrade is needed.
The best corrosion-resistance comes from Stainless Steel, however tin-coated bronze will suffice in normal outside areas.
Galvanized steel cable supports cannot be subject to an outside environment, or you will have corrosion problems.
Bending, Flexing and Vibration
In addition to vertical support, wide-range strain relief grips absorb strain from flexing, bending and vibration.
Especially valuable for machinery, heavy-duty strain relief grips connect cables to enclosures, equipment, power boxes, panel boards, portable power tools and more.
Single or Double Eye
Single Eye Grips are used for cable that are run vertically and then bend, with an available cable end to install through the grip.
Double Eye Grips are used for vertical cable runs that extend without bending.
A Locking Bale can be used when the attachment fits around a beam or pipe and can be locked in place.
Support grips are available in a large range of sizes to accommodate any requirement. Remke offers a vast selection of sizes in stock and ready to ship, or can create a custom size to your exact specs.
To determine the size grips, first, measure around the outside of the cable or cable bundle to get the circumference. Then, divide that by 3.14 to determine the diameter. Choose a grip with the exact same size as the diameter.
Encompassing the cable correctly allows for consistent holding power as the cable expands and contracts.
