Single‑Acting Spring Gate Hinge (Self‑Closing) for NWOV and PLS VPLs

This spring‑loaded, self‑closing gate hinge is crafted for platform lifts such as National Wheel‑O‑Vator (NWOV) and Porch‑Lift (PLS). It features a lubricated bearing, full‑mortise construction, and ¼‑inch radius corners. It is designed to align with commercial butt hinges and supports standard door or gate weights when properly installed. Available individually, or as a 2‑pack or 3‑pack for savings. It is strongly recommended to replace all hinges at the same time to maintain even tension and consistent performance.

Specifications:

• Size: 3½″ × 3½″
• Corner Style: ¼‑inch radius
• Material: Steel base with lubricated bearing
• Spring Type: Single‑acting (self‑closing)
• Mounting: 6 screw holes — wood screws #10 × ¾″, machine screws #10‑24 × ½″
• Maximum Door/Gate Load: ~70 lb when using two spring hinges + one butt hinge; ~90 lb when using three spring hinges (typical door/gate size up to 3′ × 7′)
• Non‑handed (usable on either side)
• Finish: Primed for Painting.

Each hinge is a precision hardware component; safe and reliable performance depends on proper installation by qualified personnel. Replacing all hinges simultaneously helps ensure uniform function and reduces uneven wear.
