IG Lintels Timber Frame Steel Lintel & Restraint Clips L7/50

Designed for use in timber frame construction the L7 lintel provides support to the outer leaf to brickwork over openings. Available for cavity widths 50mm to 105mm. Installation of IG�s L7, L7/HD and L7/XHD are all similar.All Timber frame lintels must be installed with restraining clips and a timber pinch batten to prevent rotation of the lintel during the building stage. Propping may be used to facilitate speed of construction. To achieve the loading figures shown, the L7 lintel must be secured with restraining clips and a timber pinch batten (not supplied) must be used to prevent lateral deflection (rotation) during the building stage. A single timber pinch batten 300mm long at mid span will be sufficient. IG timber frame restraint clips are supplied free of charge and must be fixed to the timber frame structure by 3.3mm x 50mm galvanised nails. Allowance should be made for the movement of the timber frame structure due to settlement and shrinkage. Lateral restraint clip should be placed at 500mm centres each side of mid span. These lintels, L7/50 are designed to work with cavity width of 50-65mm.
