JAMMY Pinchless® Boat Seat Hinge Pair

Check Price on Amazon

The JAMMY Pinchless® hinge set features a no-pinch design for smooth operation of pontoon, bass boat, or marine seating applications. Best for seating where a gentle, safe opening is a priority, such as low-profile lounge benches or family boats. The large 12.25″ seat-back and 8.05″ seat-bottom dimensions provide ample coverage and support. Corrosion-free aluminum with three stainless rivets adds strength without excessive weight. A potential limitation is the aluminum body if extremely high-load, long-term bending occurs in rugged conditions. Choose this if you prioritize pinch-free use and lighter weight.

Buying Guide

Key considerations for selecting boat-seat hinges include material, load capacity, environment, and installation method. The following questions help refine choices:

  • What environment will the hinges face? If exposed to saltwater and high humidity, choose 316 stainless steel for superior corrosion resistance.
  • Is a continuous or pin-point hinge needed? Continuous hinges offer even weight distribution and smoother pivot for long lids, while shorter hinges may fit compact compartments.
  • Do you need pinch-free operation? For seating where fingers should stay safe, consider pinchless designs like JAMMY.
  • Will you cut the hinge to size? Some hinges can be trimmed; plan for precise measurements to avoid misalignment.
  • What is the weight and size of the door, hatch, or lid? Match the hinge length, thickness, and mounting method to the load.

Installation Tips

  • Use the included screws where provided and pre-drill pilot holes to prevent splitting.
  • Check alignment before final tightening; run a test open-close cycle to verify smooth operation.
  • Seal exposed screw heads or mounting hardware to prolong lifespan in marine conditions.
