MITEK TRUSS / GIRDER BRACKETS FAST FIT MKIII (NO TAB)

MITEK TRUSS/GIRDER BRACKET FAST FIT MKIII NO TAB (GB340 & GB350)

FOR FIXING A STANDARD TRUSS TO A GIRDER TRUSS. AVAILABLE WITH OPTIONAL LOCATOR TABS APPLICATION:

The FastFit MkIII Girder Bracket can be installed with either M12 bolts or MiTek anti-split self-drilling screws for speedy installation. It is also able to accommodate scissor trusses with a bottom chord pitch up to 20 degrees.

Screws or bolts may be used with this FastFit MkIII Girder Bracket. However, each method of fixing will provide a different design capacity. The values for Screw/Cyclonic Fixing method require anti-split plates on both sides of Girder Bracket and on both faces of girder bottom chord when the chord depth is greater than 90mm. When using Screw Fixing method without anti-split plates, multiply ‘DL Only’ and ‘DL+LL’ capacities by 0.6. Use reactions from truss designs to check suitability of selected Girder Bracket. When different timbers are used in trusses, base ‘DL only’ and ‘DL+LL’ capacities on joint group of girder truss and base ‘DL+WL’ capacity on weaker joint group of girder and supported truss. If the FastFit Girder Bracket is used with the Hip Girder Bracket to support a hip truss, reduce the capacity of the FastFit MkIII Girder Bracket by deducting half the hip truss reaction.
