Shop for steel friction and limit device

This window friction and limit device is constructed from stainless steel. It features a non-handed swivel bar with stop and adjustable friction pad. This type of window friction and limit device is used by a variety of window manufacturers.

Grab Hooks have a narrow throat that "grabs" the chain between links and hold it in place. Eye type ends must be attached with a Connecting Link or other high load connection device. Hooks are sized by the chain diameter that each is used with. Use with chain of equal or lower working load limit. Material: Steel.

The VEVOR porta wrap eye sling is composed of high-quality polyester rope and stainless steel port a wrap. It has a functional bearing capacity to withstand weight up to 4409 lbs. (2000 kg). It is a rope friction device to lower heavy objects and complete the work efficiently.

SafeBloc is a triple hole thimble that adds friction in the rigging system to the top of the tree, thus adding safety by reducing rigging point stress compared to a system that uses a block or pulley. Also, with the benefit of friction, the climber can often take over on the rigging line after the groundperson controlled the initial drop. This is true on small-to-medium loads. This frees up the groundperson to use both hands and the climber can finish the lowering. Use the SafeBloc anywhere you'd use an arborist block for lowering. The rigging line can be woven through the three holes for its maximum friction, or fewer holes for less friction. However, the climber should not have to travel back to the SafeBloc to do any adjustments; just pick the friction level predicted and continue to use it. The SafeBloc does NOT add significant friction. A device that added too much friction could be dangerous and fatigue the short length of rope between the SafeBloc and the material being lowered. You can use the SafeBloc without a basal lowering device on small-to-medium loads, but once you get to medium-and-above size loads, it's time to add the basal lowering device. Lightweight and durable, the SafeBloc has no moving parts to wear out or damage, and is hard-coated for extended wear. The SafeBloc comes spliced onto an adjustable whoopie sling available in 3/4-inch Tenex from Samson. Tensile Strength: 27, 000 lbs. (120kN) Working Load Limit: 2700 lbs. (12kN). Material: Nylon.
