How To Installation?


1. Mark the Position

Decide where to place the bolt (usually at the very top or bottom of the door edge).

Trace the outline of the faceplate onto the door's edge.



2. Create the Recess (Mortise)

Chisel or Route: Carefully carve out a shallow recess (about 2mm deep) so the faceplate sits perfectly flat with the wood.

Deep Channel: Drill or chisel a deeper internal channel behind the faceplate to accommodate the main body and the sliding mechanism.



3. Install the Bolt Body

Insert the bolt into the prepared slot.

Secure it firmly using the provided wood screws through the top and bottom holes of the faceplate.



4. Install the Strike Plate (The "Keep")

Close the door and extend the bolt to mark exactly where it hits the floor or the top door frame.

Drill a hole for the bolt to enter.

Chisel a small recess for the strike plate and screw it into place to ensure a clean, secure finish.






How To Use?


1. To Lock (Engage the Bolt)

Flip the Lever: Locate the small finger lever on the faceplate (the part recessed into the door edge).

Push Up/Down: Depending on whether the bolt is installed at the top or bottom of the door, flip the lever toward the frame or floor.

Secure: The solid metal rod will extend into the strike plate (the hole in the frame or floor), locking the door leaf firmly in place.



2. To Unlock (Retract the Bolt)

Flip the Lever Back: Simply flip the lever in the opposite direction.

Clearance: The metal rod will slide back into the door body, sitting flush with the edge.

Open the Door: Once the bolt is retracted, the door is free to swing open.



3.Pro-Tips for Daily Use:

Double Doors: Typically, this bolt is used on the "inactive" leaf (the door that usually stays closed). You keep this leaf bolted shut, and only unlock it when you need to open both doors for moving furniture or extra ventilation.

Maintenance: Since these are often installed at the bottom of doors, dust can sometimes settle in the floor hole. A quick vacuum or blast of compressed air in the strike plate once or twice a year will keep the bolt sliding smoothly.





Will it fit my door's thickness?


This flush bolt is designed for standard timber and metal doors. It typically requires a door thickness of at least 35mm (1-3/8") to ensure the mortise channel doesn't compromise the door's structural integrity.






Is it made of "Real" 304/316 Stainless Steel?


Yes, this product is crafted from high-grade 304 stainless steel, providing excellent corrosion resistance and durability, making it suitable for both interior and exterior applications.






How deep is the "Throw"?


The bolt features a secure 20mm to 25mm throw (extension length), ensuring a deep engagement into the frame or floor for maximum security against forced entry.






Why Choose Us


1. Superior Material Quality

True 304 Stainless Steel: Unlike cheaper alloys that pit and rust, Degol uses high-grade stainless steel. This is essential for longevity in high-humidity areas like bathrooms or coastal regions.

Precision Manufacturing: Degol operates a 50,000+ m² workshop with automated CNC and polishing machines, ensuring every bolt has a smooth, burr-free finish and a consistent "click" feel.



2. High Stability & Security

Heavy-Duty Internal Springs: One common complaint about generic flush bolts is that they "drop" or slide down over time due to gravity. Degol’s internal tension springs are engineered to stay locked, whether installed at the top or bottom of the door.

Deep Bolt Engagement: The solid rod provides deep penetration into the frame, making it a "hidden hero" for preventing the inactive leaf of a double door from being forced open.



3. Professional Export Standards

Global Popularity: Degol exports to over 60 countries. Buying from them means you are selling a product that has already been "battle-tested" in the North American, European, and Southeast Asian markets.

99% Acceptance Rate: Their strict quality control means you won’t have to deal with the headache of customer returns due to faulty levers or misaligned faceplates.



4. Versatile Design

Aesthetic Finishes: While Satin Stainless Steel (SSS) is the most popular, Degol offers multiple finishes (Polished, Antique Brass, etc.), allowing you to cater to high-end interior designers who need hardware to match specific decor.
