All timber frame lintels must be installed with restraining clips (supplied) and should be fixed to timber frame using 3 No 3.3mm Dia x 50 long galvanized nails. The clip should overlap lintel by 12mm as indicated by a line on the clip.
Lintels above 1200 long should be propped until lintel is fully loaded and brickwork has matured. Use a horizontal timber spreader to avoid distorting lintel. Use single central prop for openings up to 2100. For larger openings use multiple props (max spacing 1200).
