Designed for use in Timber Frame construction, the
L7 lintel provides support to the outer leaf to
brickwork over openings.
To achieve the loading figures shown, the L7 lintel
must be secured with restraining clips and a block
/batten (not supplied) must be used to prevent
lateral deflection (twist) during the building stage.
A single block/batten 300mm long at mid span will
be sufficient. Restraining clips should be fixed with
3.3 x 50mm galvanised nails at no more than 500mm
centres each side of mid span.
Clips should be positioned with their vertical centres
at the top of the lintel to allow for lintel movement
and shrinkage of timber frame.
