How to install a B&D Roller Door into Steel Shed with steel jambs. Most Roller Doors will be very similar. If the jambs were timber or brick the fixing screws shown here will be swapped out for something appropriate such as coach bolts or masonry anchors.
Please note that we recommend a 30 mm door curtain overlap each side for steel jambs like these due to the rolled jamb edge. This means that the Door Opening equals the Door Curtain size minus 60 mm (for small residential non wind-locked doors).
