GMS Checkerplate (Boltdown)

This range of hot dipped Galvanised Mild Steel covers are manufactured to sit into the rebate of our lightweight GRC cable pits. The checkerplate covers are slip resistant (P3 to AS4586) and when paired with our locking system they prevent opportunistic access – patented high security bolts are available if required.  The locking system is ‘barless’ to ensure a larger clear opening and no additional components that can be lost.

Available in up to Class C as standard stock items, a Class D (with frame) is available if required.
