The Nash Trigger Cleat has a unique mechanism that allows you to release highly loaded lines with complete control. Pulling the sheet down on the trigger trips the pawls and frees the sheet. The trigger serves as a snubbing surface to control the release.
In light air, or once the trigger releases the load, the cleat operates like a normal cam cleat. The trigger cleat is constructed of rugged stainless steel. It is very reliable in heavy air.
Trigger cleats are ideal on highly loaded systems like mainsheets, vangs, control lines, and even some halyards. They have developed a cult-like following in some classes, where the crew loves the ability to spill the mainsail reliably during close-quarters maneuvering.
This cleat is generally mounted on the deck, or on a swivel base.
