LUGT3
The LUGT series is an adaptable tiedown for girder trusses
and offers several installation options to accommodate
different framing conditions. It is an ideal retrot solution to
reinforce truss connections to transfer high wind loads to
supporting walls and can be used on either concrete or CMU
block walls. Sizes available for 2-ply, 3-ply and 4-ply trusses.
Materials: See chart
Finish: G90 galvanizing
Installation:
• Use all specied fasteners. See Product Notes, page 18.
• All large fastener holes must be lled with specied
fasteners to achieve loads listed in the chart. Smaller
fastener holes are for girder-to-stud applications
(reference page 257) and do not need to be lled when
used for concrete/masonry installations.
• MiTek’s WS structural wood screws are included with
LUGT3 and LUGT4.
• For concrete and masonry applications,
a moisture barrier may be required, check
local building code.
