TACO Marine Command Ratchet Hinges, 18-1/2 in, Polished SS316L, 61.5 Degree Lock, Pair

Overview

The TACO Marine H25-0023 is an 18-1/2" Command Ratchet Hinge pair for boat seating applications such as sun pads, bolsters, and lounge backrests. It uses polished Type 316L stainless steel with brass bearings and has one locking position at 61.5 degrees, giving longer backrests a fixed support angle without the look of exposed brackets.

This hinge set is made for longer seating layouts, with support for seatbacks up to 22" long and cushions up to 4" thick. It is a practical fit for cockpit lounges, aft sun pads, pontoon seating, and custom helm or deck seating where the backrest needs to lift, ratchet, and return to horizontal.

Installation and fit

These hinges mount above deck and work well in seating areas where the hardware remains visible, such as lounge modules, sun pad assemblies, and raised backrest sections. The countersunk mounting pattern accepts #10 fasteners or 1/4-20 bolts, so the final fastener choice should match the seat structure, backing material, and load path on the boat.

Because seating hardware sees movement, vibration, and shifting passenger weight, the hinge pair should be installed on a sound mounting surface with proper backing where needed. Check the backrest length, cushion thickness, hinge spacing, and clearance through the full range of motion before final drilling.

Materials and use on board

The polished 316L stainless finish suits exposed seating hardware in cockpits, swim platform lounges, bow seating, and other wet areas where appearance and corrosion resistance both matter. Brass bearings add support at the pivot point, while the salt fog test rating gives useful confidence for boats that live around spray, washdowns, and coastal air.

This pair is a good match for owners, builders, and refit shops working on longer marine seatbacks that need a clean ratcheting support rather than a loose cushion or separate prop arm. It keeps the hardware simple, visible, and serviceable while giving the backrest a defined raised position.
