How to Use Webbing Grips

Wrap Grips are designed for tensile testing of cordage - ropes, straps, thread, webbing, and wire. The flexible material is wound around the wrapping column and then secured prior to the tensile test. Mountain climbers often will select ropes based on two criteria, rope strength, and weight. Testing rope strength and other cordage and webbing tensile strengths should be done with an appropriately sized wrap grip.

These grips are slightly more robust than the smaller versions. To attach a webbing, guide the end through the center opening and wrap the sample on top of itself. Secure the ribbon by using the locking pin.

The largest webbing grips use two locking pins instead of one. There are several different sizes for the center drums. Other options include substitute metals suitable for environmental chambers, and knurled or bumpy cylinder surfaces.
