VersaChock’s patent pending double wide blind fastener kit is designed exclusively for use with VersaChock oval threaded deck plates (VC5DECKPLATE/VC65DECKPLATE), which can be used with standard eyebolts and bolts for attaching and securing custom chocks and deck hardware. The system allows for deck plate installation when access to the backside of mounting surface is not possible. It also serves as a backing plate. Perfect for solo installations when a second set of hands is not available! Made of high quality 316 stainless steel. 1/4" oval head screws, installation stud and tie strap included. Patent/s pending.
