PRODUCTS MUST BE FITTED IN ACCORDANCE WITH CLARK-DRAIN INSTALLATION GUIDES. QUESTIONS I M INSTALLING A 450MM MANHOLE COVER OVER AN INSPECTION CHAMBER AND THE DEPTH IS OVER 1.2M, WHAT SHALL I DO? Use the CLKS 499 Reducer, this fits on all our 450mm dia polypropylene covers and will reduce the opening to 350mm to comply with the Building Regulations. WE HAVE A BROKEN COVER DO YOU DO A 26 X 20 MANHOLE COVER? DO YOU DO A 650MM X 550MM COVER? All manhole covers and frames are measured by the clear opening, as this is the only true constant between manufacturer s designs. The above covers will be a 600mm x 450mm (24 x 18 approx) clear opening cover. DID YOU KNOW WE GET 5 CALLS A DAY EACH ASKING THIS QUESTION? SAVE YOUR TIME AND OURS AND SUPPLY FROM STOCK. I M FITTING A 450MM INSPECTION CHAMBER COVER IN MY DRIVEWAY AND MY GARDEN AND DO NOT KNOW WHICH ONE TO USE, CAN YOU ADVISE? You should use the CLKS 452 Polypropylene cover which complies with Doc H of the Building Regulations OUR 2 TONNE FORKLIFT HAS JUST BROKEN A 10 TONNE GPW STEEL MANHOLE COVER. WHY HAS THIS HAPPENED? Forklifts have smaller diameter tyres and a smaller contact area than standard road going vehicles. Calculations show that they apply at least 4 times the load of a 10 Tonne lorry plus extra dynamic forces due to solid tyres, little suspension etc. Clark-Drain recommends the use of our forklift loading covers for use in typical forklift loading areas.
