The EMNKAPAK is a lockable clear lid cover that fits over most 22mm pushbuttons, spring-loaded to snap shut automatically once released. Unlike a simple guard ring, it can be locked, giving a genuine barrier against unauthorised or accidental operation rather than just knock protection. It’s priced well below premium-brand equivalents and held in UK stock for fast dispatch.
Prevents accidental operation. Avoids mechanical shocks and damage. Easy to fit components with anti-rotation notch.
Use in accordance with relevant codes of practise.
The cover suits EMAS 22mm emergency stops with heads up to 40mm:

Can I see the button through the closed lid?
Yes the lid is clear, so the button’s colour and any illumination remain visible even when the cover is closed.
What size buttons does it fit?
