Installation Method


1.Mark the Mortise: Position the heavy duty door hinge on the edge of the door and the frame, tracing around the leaves with a pencil to mark where the wood needs to be recessed.


2.Chisel the Recess: Use a wood chisel to remove the material within your marks until the hinge leaf sits perfectly flush with the surface of the door and frame.


3.Drill Pilot Holes: Align the hinge in the recessed area and use a drill to create pilot holes for all eight screw locations to prevent the wood from splitting.


4.Secure the Leaves: Fasten the hinge leaves firmly into place using high-quality stainless steel screws, ensuring the ball bearing knuckles are oriented correctly for the door's swing direction.


5.Hang the Door: Lift the door into position, align the hinge leaves on the door with those on the frame, and insert the hinge pins (if removable) or finish securing the remaining screws.


6.Final Check: Open and close the door to verify that the soft close movement is silent and that the gaps around the door remain consistent.




Applicable Scenarios


1.Daily Use and Maintenance

Load Distribution: For standard interior doors, use two hinges; however, for heavy duty solid-core or fire doors, install three hinges to prevent the door from warping or sagging over time.

Silent Operation: The integrated ball bearings are permanently lubricated to ensure a smooth, friction-free swing every time you open the door.

Surface Care: Wipe the brushed stainless steel finish with a soft cloth periodically to maintain its sleek, professional look and remove any accumulated dust.

Avoid Overloading: Do not hang heavy objects (like heavy coats or bags) on the door handles, as this puts unnecessary vertical stress on the hinge knuckles.

Annual Inspection: Once a year, check that the mounting screws remain tight and ensure the hinge pin is fully seated to maintain the soft close feel.


2.Maintenance Tips

No Grease Needed: Because these are ball bearing hinges, you generally do not need to apply messy oils or WD-40, which can actually attract dirt and gunk up the mechanism.

Cleaning: If the hinges are used in a coastal or humid environment, a light wipe with a silicone-based spray can provide an extra layer of protection for the stainless steel 304 surface.




Why It Stands Out


1. Advanced Ball Bearing Technology

Unlike standard "plain bearing" hinges that rely on metal rubbing against metal, Degol uses precision-engineered ball bearings.

Silent Operation: The bearings eliminate friction, ensuring the door opens and closes with a whisper-quiet, "soft close" feel.

Reduced Wear: By distributing the weight of the door across internal steel balls, the hinge prevents "metal dust" buildup and the common "hinge sag" over years of use.


2. Heavy-Duty Stainless Steel Construction

Degol specializes in stainless steel 304, a material far superior to the zinc or aluminum alloys used in budget hardware.

Superior Load Capacity: This heavy duty door hinge is designed to support the weight of thick solid-core, fire-rated, or metal doors without bending or snapping.

Corrosion Resistance: The high chromium and nickel content makes these hinges virtually rust-proof, even in humid bathrooms or coastal exterior applications.


3. Aesthetic Consistency for Modern Spaces

A cohesive look is essential for high-end interior design.

Sleek Brushed Finish: The satin finish on these hinges is meticulously matched to Degol’s modern interior door handle sets and sign plates, creating a unified hardware theme throughout a building.

Low-Profile Knuckles: The precision-machined joints provide a slim, professional silhouette that complements modern minimalist signage and decor.


4. Certified Manufacturing Quality

As a product of Jiangmen Degol Hardware Co., Ltd., these hinges are manufactured under strict quality control.

Precision Drilling: The 8-hole symmetrical pattern ensures even weight distribution and a secure grip on the door frame, making it a reliable replacement door hinge.

Proven Durability: These hinges are tested for high-cycle opening and closing to ensure they meet the demands of commercial and luxury residential use.
