This is our 316 stainless steel Bimini Top Hinged jaw slide fitting for 7/8” (22mm)
These are used in a variety of ways.
A couple of the most common is to add a Bimini top to boat rails or to add support arms to an existing top.
This jaw slide has 2 Phillips head bolts to secure it to the rail.
Once the fitting is secured to the rail the distance between the posts will be about ¼” wide, the industry standard.
