Why You Should Use Spring Loaded Door Hinges?
Spring loaded hinges ensure doors automatically return to the closed position, improving energy efficiency, fire safety, and building security. Unlike bulky closers, Waterson's hinges feature a compact, integrated design that preserves your door's aesthetic.
Spring loaded hinge vs. overhead door closer
Waterson spring loaded hinges replace one or two of the standard hinges on your door — no separate bracket, arm, or additional fasteners needed. Compared to a traditional overhead closer:
- No visible hardware above the door — cleaner aesthetic
- Full door clearance maintained — no arm reducing headroom
- No exposed mechanism — vandal resistant
- Low opening force — ADA compliant out of the box
- Same UL fire rating — meets NFPA 80 self-closing requirements

How Many Spring Hinges do I Need?
- 2 hinges for ≤60" or <150 lbs
- 3 hinges for 60–90" or 150–330 lbs

Frequently Asked Questions
Is a spring loaded hinge self-closing?
Yes. The internal spring drives the door back to the closed and latched position every time. Hydraulic models add fluid damping so the door closes without slamming. Both types meet NFPA 80 and ADA closing force requirements.
How do you adjust tension on spring loaded door hinges?
Waterson hinges use a numbered tension panel on the hinge leaf. Use the included tension crook to increase or decrease closing force — start at setting #3 for most standard doors. On hydraulic models, a secondary screw adjusts closing speed independently of spring tension. Always adjust one hinge at a time, starting from the top.
Do spring loaded hinges work on heavy doors?
Yes. The 4.5"×4.5" models support up to 260 lbs with 3 hinges, or 330 lbs with 4 hinges. The 5"×5" models support up to 440 lbs and are rated for doors up to 2¼" thick. Contact us if your door exceeds these specs.
What is the difference between spring hinges and hydraulic hinges?
Both self-close. Spring-only (mechanical) hinges close with consistent force — good for fire doors and utility rooms. Hydraulic hinges add a fluid damper that slows the final closing motion, preventing slamming — better for restrooms, offices, and hospitality spaces.
