A Gripple wire joiner is a device used to join and tension wire, to terminate and suspend wires and wire ropes, and also to support false ceilings, cable baskets, and similar items.
Wire salesman Hugh Facey invented the original "Gripple" wire tensioner and joiner after a conversation in 1986 with a Welsh farmer. The first Gripple wire joiner was launched in the UK in 1988, and Gripple Ltd was established in 1991.
Wire or wire rope is inserted into a channel in the Gripple wire joiner, where it is gripped by a spring-loaded roller or wedge, and tensioned by being pulled through. The channel is mirrored on the opposite side of the Gripple wire joiner, allowing a second piece of wire to be joined.
By turning a Gripple wire joiner through 90 degrees and combining it with wire rope, it produces a suspension system capable of holding up substantial loads, and this has given rise to a range of Gripple suspension systems, which are sold to the construction industry worldwide.
