The knob design affects the user’s grip, ease of operation, and even the overall durability of the lock. Here’s a rundown of common knob shapes and their benefits for four-digit code cam locks:

3. T-Handle Knob:

• Shape and Design: Shaped like a “T” for better leverage when turning, making it ideal for larger or more secure locks.

5. Lever Knob:

• Shape and Design: Features a lever or “wing” shape, which makes it easy to turn with minimal effort.
• Accessibility: Particularly user-friendly and accessible, as it requires less grip strength to operate.
• Best Applications: Often used in environments where users may have reduced mobility, such as senior facilities or high-traffic lockers.
