1. Mark the Hinge Positions Standard placement for residential doors is usually 5–7 inches from the top and 10–11 inches from the bottom. If using a third hinge (recommended for heavy stainless steel hinges), place it exactly in the middle of the top and bottom ones. Mark these levels on both the door edge and the door frame.
2. Trace the Outline Hold one leaf of the hinge against your mark on the door edge. Ensure the knuckle (the pin part) is slightly proud (extending past) of the door edge so it can swing freely. Trace the perimeter of the hinge leaf accurately with a sharp pencil or score it with a utility knife.
3. Create the Mortise (The Recess)
Chisel the border: Use a hammer and chisel to tap along your traced lines. The depth should match the thickness of the hinge leaf.
Remove the waste: Make a series of shallow "V" cuts across the grain within the marked area, then carefully shave the wood out until the area is flat and at the correct depth.
Test fit: The hinge should sit perfectly flush with the wood surface.
4. Drill Pilot Holes Place the hinge in the mortise and mark the center of the screw holes. Use a drill bit slightly smaller than your screws to drill pilot holes. This prevents the wood from splitting, especially with hard woods or near the edge.
5. Secure the Hinges to the Door Drive the provided stainless steel screws into the door. Ensure the heads are flush so they don’t interfere with the hinge closing.
6. Attach to the Door Frame Prop the door up in the frame using wedges to maintain a 3mm gap at the top. Align the hinge leaves with the marks on the frame, repeat the mortising process on the frame (jamb) if it's a new installation, and screw them in place.
1. Initial Operation (The "Break-in")
Check for Friction: After installation, swing the door fully multiple times. You should feel zero resistance. If the door "springs" back or feels tight, the hinges are misaligned.
Verify Clearance: Ensure there is a consistent 2-3mm gap between the door and the frame. If the gap is uneven, the ball bearings will be under uneven "axial load," which can cause premature wear.
2. Load Management
Weight Distribution: For standard solid-core doors, always use three hinges. The top hinge carries the most tension, while the bottom hinge handles the compression. Ensure the middle hinge is perfectly centered to prevent the door from "bowing" over time.
Do Not Overload: These 304 stainless steel hinges are heavy-duty, but if you are using an extra-heavy security door (over 100 lbs), ensure you are using the 4-inch or larger variant to maintain smooth rotation.
3. Periodic Maintenance (Twice a Year)
Cleaning: Use a damp, soft cloth to wipe away dust from the ball bearing races (the circular joints). In coastal or high-humidity areas, salt or grime can get trapped in the bearings, causing a "grinding" feel.
Lubrication: Even though ball bearing hinges are often pre-lubricated, a drop of silicone spray or light machine oil (like 3-in-1) applied to the top of the pin every 12 months will keep the internal balls rolling effortlessly. Avoid heavy grease, as it attracts grit that can act like sandpaper inside the bearing.
Screw Tightening: Wooden doors naturally expand and contract with the seasons. Use a screwdriver to check that the hinge screws remain snug. A loose screw on the top hinge is the #1 cause of "door sag."
4. Safety & Security
Pin Inspection: If your hinges are "removable pin" types and installed on an exterior door, ensure the pin is fully tapped down. For maximum security on outward-swinging doors, ensure you have used a "Non-Removable Pin" (NRP) version or a security stud.
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.
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.
1. Professional Grade Materials
Degol uses full-material 304 stainless steel, which is significantly more durable than the common 201 grade or iron alternatives. This ensures the hinges are:
Highly Rust-Resistant: Specifically designed to cope with humid environments like bathrooms, kitchens, and coastal areas.
Surface Perfection: Their manufacturing process ensures "no sand holes" on the surface, providing a flawless, high-end brushed or polished finish that complements modern architectural styles.
2. Frictionless Ball Bearing Technology
Unlike standard butt hinges where metal rubs against metal (causing that annoying black graphite dust and eventual sagging), Degol’s hinges feature integrated ball bearings.
Whisper-Quiet: The bearings act as a buffer, eliminating the metal-on-metal grinding that causes squeaks.
Effortless Operation: They turn heavy doors into "light" ones, allowing them to swing open with minimal force—ideal for high-traffic areas in both homes and commercial buildings.
3. Heavy-Duty Load Capacity
These hinges are engineered for architectural stability. The use of reinforced steel and precision-fitted pins means:
Anti-Sagging: They maintain door alignment over years of use, preventing the door from dragging against the floor or frame.
Versatility: Suitable for everything from heavy solid wood entry doors to sleek metal interior doors.
4. Cost-Effective Longevity
While the initial investment is slightly higher than basic hinges, the total cost of ownership is lower. Because they don't wear down or rust, you save on:
Replacement costs.
Maintenance time (no need for constant oiling).
Repairs to door frames caused by sagging.
