Compatible with YakAttack MightyMount's, GearTrac, and most other kayak track systems from Scotty Fishing Products, RAM Mounts, and YakGear. For FeelFree Kayaks, 3 Water Kayaks, and Jonny Boats you will need an adapter to be compatible. We offer the needed adapter in a single pack (AAP-1012) and a six pack (AAP-1012-6). The GT Cleat makes for a perfect companion to our highly popular LeverLoc Anchor Trolley and is a low profile, easy to attach and adjust anchor line cleat. The underside of the cleat features two tabs and a rubber washer helping keep the cleat from rotating and sliding in the track from anchor line tension.
