Security Fittings - 303 & 304
High quality security grubscrews, part 303, designed with a unique central recess. This means they can't be inserted or removed with a standard allen key giving added protection against the removal of installations by thieves or vandals. They can only be used in conjunction with the appropriate security key, part no 304.
We are sorry but the allen key for the 1/4" grubscrew to fit tube size 26.9mm and 33.7mm is currently out of stock. Apologies for any inconvenience caused.
then we’re just a call away
