Wavin WAJ Access Chamber Riser - 315mm

The Wavin WAJ Access Chamber Riser - 315mm can be fitted directly to a WAJ inspection junction base to increase the invert depth. When fitted with a frame and connected to a WAJ inspection junction base, it gives an invert depth of between 370mm - 440mm. A shallower depth can be achieved by cutting the riser with a fine tooth hand saw. The circumference grooves at 30mm spacing act as a cutting guide. The incorporated ring seal prevents leakages.
