The Endurotek technology has been developed by Terra Firma with a uniquely formulated compound to ensure the product retains shape and gives years of great service. Moulded as a single, solid thermoset structure Terra Firma Endurotek pit lids take safety and reliability to the next level.

Installation is also easier and quicker! The Terra Firma Slam Lock ™ ensures lids are always locked and secure. No need to use a key to lock the lid, just drop the lid into the frame and the Slam Lock does the rest. Terra Firma manhole covers fitted with Slam Lock are quicker and easier to install. The Terra Firma Slam Lock is built to lock within the frame. The innovative system eliminates the need to form a lock cavity in pit walls.

Terra Firma Endurotek can be opened using most common keys – including all Telstra and Gatic-style lifters. Endurotek completely eliminates the need for specialist keys while the slam lock ensures lids are never left unlocked again.
