The 6 Components Every Reliable Vehicle Closure System Needs
Dust, water ingress and vibration issues are rarely caused by one component alone. A reliable closure system depends on the right combination of seals, locks, hinges, struts and hardware working together.
Compression Locks
Pinchweld & Seals
Hinges
Gas Struts
Fasteners
Whale Tail Locks
Why Sealing Performance Is More Than Just a Rubber Seal
A seal can only perform properly when the surrounding hardware supports it. If the door is poorly aligned, under-compressed or not securely fastened, dust and water can still find a way in.
The best results come from treating the door, frame and hardware as one complete system.
The Key Components
1. Compression Locks
Compression locks help pull doors tightly against the seal, maintaining consistent pressure and reducing rattling, movement and exposure to dust or water.

2. Pinchweld & Seal Profiles
Seal profiles create the barrier between the door and frame, helping reduce dust, water entry and vibration when correctly selected and compressed.

3. Hinges
Hinges support alignment over time. Poor alignment can cause uneven compression, seal wear and reduced protection against the elements.

4. Gas Struts
Gas struts provide controlled opening and closing, improving usability while reducing stress on hinges and mounting points.

5. Fasteners
Fasteners help maintain structural integrity and ensure locks, hinges and seals remain securely mounted under vibration and regular use.

6. Whale Tail Locks
Whale tail locks provide secure access for vehicle bodies, canopies and service compartments while maintaining a clean external appearance.

Before Finalising Your Build
Ask these questions before specifying your hardware:
- Have you selected the correct seal profile?
- Is there enough compression on the seal?
- Are the hinges suitable for the door size and weight?
- Is controlled opening required?
- Have appropriate fasteners been specified?
- Is the locking solution suitable for the application?
