1.Piano (Continuous) Hinge Installation
A piano hinge runs the full length of a door or lid to distribute weight evenly.
Cut to Size: Measure the length of your door or frame and cut the hinge with a hacksaw. File the cut ends until smooth.
Positioning: Clamp the hinge to the door leaf or frame first. The round "knuckle" of the hinge should sit just outside the edge for a full swing.
Pilot Holes: Use a self-centering drill bit (Vix bit) to ensure holes are perfectly centered.
Initial Fastening: Drive a minimum number of screws—one at each end—to check the fit before driving the rest.
2.Pivot Hinge Installation
Pivot hinges allow doors to swing from a central point rather than the side.
Mark Pivot Points: Mark the top and bottom pivot locations on both the door and the frame, ensuring they are perfectly aligned vertically.
Install Bottom Hardware: Secure the hinge plate to the floor or threshold. Attach the corresponding pivot component to the bottom of the door.
Install Top Hardware: Attach the top pivot to the header (top frame) and the corresponding component to the top of the door.
Hang and Adjust: Lift the door onto the bottom pin, then align the top pin. Most pivot hinges have adjustment screws to help level the door.
3.Double Action Spring Hinge Installation
These hinges allow a door to swing in both directions and automatically return to a closed position.
Release Tension: Before mounting, use the provided tension rod to release the tension on the springs and remove the tension pins.
Mount Hinges: Attach the door leaf to the door first, then align the door with the frame and attach the jamb flange.
Set Tension: With the door closed, use the tension rod to turn the tension lug. Insert the tension pin to lock the desired closing force.
Test and Shim: Check if the door sags; if it does, increase tension on the top hinge or use shims to correct the alignment.
Feature | How to Use It |
Length | Cut with a hacksaw to match your door/lid exactly. |
Screws | Fill every hole. Skipping holes weakens the continuous support. |
Alignment | Use a "Vix bit" (self-centering bit) so the hinge doesn't shift when you tighten the screws. |
Swing | Ensure the barrel is slightly offset from the edge so the door can open past 90 degrees. |
The gap between the door and the floor typically needs to be between 5mm and 10mm to allow the pivot mechanism to function smoothly while maintaining a sleek, hidden appearance.
No, the floor plate is designed to be low-profile or recessed. Because it is installed at the axis point (usually in a corner), it stays out of the foot traffic path, making it safer than protruding door stops.
The product features a high-quality brushed stainless steel finish. This clean, modern look is designed to match other professional-grade 304 stainless steel handles and locks.
1. Superior Surface Integrity
"No Sand Hole" Guarantee: Degol emphasizes a surface free of sand holes (tiny pits caused during the casting process). This creates a mirror-like or perfectly brushed finish that doesn't trap moisture or dirt, which is a common failure point in cheaper cast hinges.
Full Material Construction: Unlike "hollow" or plated-thin hinges, they use solid-core materials (304 Stainless, Brass, or Iron). This ensures the hinge won't bend or warp under the weight of heavy solid-wood doors.
2. Silent & Smooth Engineering
Frictionless Movement: Their hinges are engineered for silent operation. They utilize precision-ground knuckles and, in their ball-bearing models, lubricated internal bearings that prevent the "metal-on-metal" grinding sound over time.
Precision Pivot: The pins are tightly fitted to the leaves, reducing "hinge play" (the slight wobbling movement that causes doors to sag or misalign with the latch).
3. High Environmental Resistance
Anti-Corrosion Coating: Degol products are designed to handle humid environments like bathrooms or coastal areas. Their 304 Stainless Steel series is specifically treated to resist rust and abrasion.
Finish Variety: They offer advanced plating in finishes like Antique Brass (AB) and Satin Stainless Steel (SSS) that are bonded to the metal, meaning they won't flake or peel with heavy use.
4. Safety-First Design
Burr-Free Edges: A signature of their manufacturing is the "hand-safe" finish. All edges are smoothed down during production so there are no sharp metal burrs that could cut you during installation or snag on clothing.
