Head Box - Drawing ID 01/02
Side Guides - Drawing ID 01/02
• The head box is manufactured from mild steel sheet, which depending on the
length may come in pre-assembled sections. Each part of the head box is
clearly marked inside. All roller support brackets and hood support brackets
must be installed in the pre-drilled locations.
• Position the back cover of the box to the structure in accordance with the
dimensions and fixing detail indicated on the approved drawing. It is important
to use the central anchor point and position each bolt to the extremity of
each slot as the product must expand either side of the anchor point in a fire
situation.
• Check the box housing is level with a spirit level or laser device, mark the fixing
holes and drill for the specified fixing type.
• Lift the box housing and fix to the structure using the fixings and fusible
washers. Carry out a final check to ensure the box housing is level. If the box
housing is not installed level this will result in the fabric travelling sideways
along the roller tube when retracting. This will result in the curtain snagging.
• When smoke seals have been supplied they must be riveted to the head box
using steel rivets into the pre-drilled holes, if the housing has been supplied in
sections. Housings supplied in one section will have the smoke seals factory
fitted.
Now position the back section of the guide to the structure with the top edge
entering into the head box housing by 40mm. Use a spirit level or laser device
and set the guides plumb to the correct dimensions indicated on the working
drawing. Mark the fixing holes at the top of the slots to allow for expansion.
Drill for the specified fixing type.
Fix to the structure using the fixings and fusible washers. If required the guide
must be suitably shimmed to ensure they remain vertical without any twisting.
