Dust plugs are a simple and highly effective way to prevent dust and dirt ingress into key interlocks. Made from high density polyethylene (HDPE) and fitted with a ‘soft sealing’ aperture gasket, the plug is inserted into the key aperture as soon as one of the coded keys is removed.

Vinyl bags are robust covers that envelop the complete interlock unit and protect key aperture points and lock bodies. Weather- and dust-proof, they also have UV protection.
