18  (21.60 inc. VAT) quantity:  


The Vent Cap is placed into the upstand secured to the tank, using the supplied grub screw, followed by a shear screw. The shear screw is designed to break away from the vent when fully tightened, leaving a flat, clean surface which makes it difficult for thieves to use as a lever point to gain access to the tank.

Equipment Specification

* Weatherproof Vent Cover

* Shear Bolt
* Fitting Instructions
