A marine rectangular rail base (90°) is a perpendicular deck fitting used to mount vertical stanchions, handrails, grab bars, and T-top frames completely upright and straight at a 90-degree angle to the boat's mounting surface.
Key Technical Specs

Tubing Attachment: Features two internal Allen set screws positioned at a 90-degree offset to bite into the tube and eliminate twisting.
