Forget flimsy hinges that squeak or rust—this stainless steel option delivers. Forged from corrosion-resistant metal, it glides smoothly with every door swing, no creaks to disrupt quiet spaces. Pre-drilled holes cut installation time (no special tools needed), and it locks into standard frames for a wobble-free hold.Its polished finish slips into any interior—modern homes, busy offices, small retail spots—without clashing. Built to last, it shrugs off wear and moisture, so upkeep is minimal. This isn’t just hardware; it’s the reliable, low-fuss backbone your doors need to stay steady, day in and day out.

1. Preparation and Positioning
Identify the Swing: Determine if your door swings left or right. Most of these hinges are template-drilled, meaning they should line up with standard hinge cutouts.
Mortising: If you are replacing a standard hinge, the "leaves" (the flat plates) should fit into the existing recesses. If this is a new installation, you will need to chisel out a mortise on both the door and the frame so the hinge sits flush.
2. Mounting the Hinge
Attach to Door: Screw the hinge leaves onto the door first. Use the long screws provided to ensure they grab the solid wood of the door.
Attach to Frame: Align the door with the frame. It’s helpful to have a second person hold the door or use shims at the bottom to keep it level while you drive the screws into the door jamb.
Pro Tip: Use at least one "extra-long" screw (2.5 - 3 inches) per hinge that reaches past the jamb and into the wall stud for maximum stability.
3. Adjusting the Tension
The hinge won't "self-close" until you set the internal spring. You will see a hole at the top of the hinge cylinder (the barrel).
Insert the Hex Key: Use the Allen wrench (hex key) that usually comes with the hardware. Insert it into the tension hole at the top.
Turn to Increase Tension: Rotate the wrench clockwise. As you turn, you will feel the spring tighten.
Insert the Locking Pin: While holding the tension with the wrench, insert the small metal "locking pin" into one of the visible slots in the barrel to hold the spring in place.
Test the Swing: Open the door and let it go. If it doesn't close all the way, move the pin to the next slot to increase tension.
1. Identify the Adjustment Points
Look at the top of the center cylinder (the barrel). You will see:
A Hex Socket: A hexagonal hole for an Allen wrench.
Adjustment Holes: Small round holes around the rim of the barrel.
The Locking Pin: A tiny metal pin (usually included in the box) that sits in one of those holes.
2. How to Increase Closing Force
If the door isn't closing all the way or staying latched, you need more tension:
Insert the Hex Key: Put the Allen wrench into the top socket.
Turn Clockwise: Rotate the wrench clockwise. This winds the internal spring.
Move the Pin: While holding the tension with the wrench, you will see the adjustment holes move. Pull the locking pin out (use pliers if it’s tight) and move it to a hole further to the right.
Release Slowly: Gently let the wrench rotate back until the pin catches against the frame of the hinge.
3. How to Decrease Closing Force (Stop Slamming)
If the door slams too hard, you need to "relax" the spring:
Take the Weight: Insert the hex key and turn it slightly clockwise just to take the pressure off the locking pin.
Reposition the Pin: Pull the pin out and move it to a hole further to the left.
Test: Release the wrench slowly. The door should now close with less force.
It is compatible with most hard surfaces like wood, tile, or marble. However, if you have underfloor heating, you must be careful when drilling into the floor to avoid damaging the heating elements.
Yes, because it is made of solid 304 stainless steel, it is designed for heavy-duty performance. Since the weight is transferred directly to the floor rather than the frame, it prevents heavy doors from sagging or drifting over time.
The hinge itself provides structural protection for the door, but because it allows for 360-degree rotation, it does not have a built-in "stop". To protect your walls from impact, you should pair this hinge with a separate door stopper.
1. High-Precision Tension Control
Unlike cheaper spring hinges that only have 2 or 3 tension settings, Degol hinges typically feature a multi-hole adjustment barrel. This allows you to fine-tune the closing speed perfectly—preventing the door from slamming while still ensuring it latches securely.
2. Heavy-Duty "UL Listed" Standards
Many Degol hinges are fire-rated and UL listed. This is important because:
Fire Safety: They are designed to ensure fire doors (like the one between your garage and house) stay closed to prevent the spread of smoke and flames.
Weight Capacity: They use thicker steel plates than standard residential hinges, meaning they won't sag or squeak even with heavy solid-wood doors.
3. Integrated "Torsion" Mechanism
The internal spring in a Degol hinge is a torsion spring, which provides a smoother "push" than standard compression springs. This makes the door feel more natural when you open it manually, rather than feeling like you are fighting against a stiff piece of metal.
