How to Choose the Right Swing Handle Lock for Large Format Enclosures

1. Start With Door Size and Weight

• < 400 mm / < 10 kg → a compact single-point swing handle is usually sufficient

• 400–800 mm / 10–20 kg → a medium-duty swing handle; consider two-point latching if the door is thin or flexible

• > 800 mm / > 20 kg → a heavy-duty handle with multi-point rod control

If the door gap varies by more than 3 mm across the closing edge, use multi-point locking.

2. Single-Point vs Multi-Point

Single-point is fine when the door is flat, warpage is minimal and sealing is not critical. Multi-point is required for wide doors, outdoor/dusty environments, wind load or vibration.

3. Key Lock Options

• Keyed cylinder: keyed-alike or keyed-different, with replaceable cylinders for easy re-keying across a cabinet fleet

• Padlock hasp: extra security for outdoor sites

• Non-locking T-handle: clean rooms and food processing

4. Material and Surface Treatment

• Indoor control panel → zinc alloy, zinc plated

• Outdoor telecom cabinet → zinc alloy, UV-stable powder coat

• Marine / coastal → SS304 brushed / passivated

• High-corrosion chemical → SS316 electropolished

• Food processing → SS304 mirror polish / hygienic

5. Panel Thickness

Standard swing handles fit 1.5–3.0 mm panels. Thicker panels up to 6 mm need extended-shaft variants or custom bushes.
