LGUM Light Face-Mount Girder and Beam Hanger for Concrete and Masonry
Product Details
The LGUM is designed for hanging girder trusses, solid sawn and EWP onto concrete or masonry. This face-mount hanger installs into the wood member with Strong-Drive® SDS Heavy-Duty Connector screws and into the masonry with Titen HD® anchors. The LGUM is available in skews up to 45°.
Key Features
- SDS screws and Titen HD anchors included
- LGUM-series hangers are tested, load rated and code compliant
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed
Material
- 12 ga.
Finish
- Galvanized. Some products available in stainless steel; see Corrosion Information.
Installation
- Use all specified fasteners (included). Stainless steel models are packaged with 1" longer Type 316 stainless-steel Titen HD anchors.
- Attach hanger to a concrete or grout-filled CMU wall using Titen HD anchors. Note the following:
— Drill holes using drill bits equal in diameter to the specified Titen HD anchor.
— Holes shall be drilled 1/2" deeper than the specified Titen HD length (e.g., 4 1/2" for a 4"-long Titen HD anchor). For stainless-steel LGUM models installed onto 6"-thick concrete or GFCMU, care should be taken to avoid damage to the back side of the wall when drilling and installing 5" long stainless-steel Titen HD anchors
— Caution: Oversized holes in the base material will reduce or eliminate the mechanical interlock of the threads with the base material and will reduce the anchor's load capacity. - The carbon-steel Titen HD is not recommended for exposed exterior applications.
- Provide moisture barrier between beam and wall per jurisdictional requirements.
Options
- For stainless-steel options see Simpson Strong-Tie® engineering letter L-C-CMUHGRSS
- Available in skews up to 45°. See table for reduced loads.

Load Tables
For stainless-steel fasteners, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
- Tabulated uplift loads are based on 4" minimum distance to top of wall.
- Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
- Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
- LGUM must be installed on minimum 6"-thick wall and HGUM on minimum 8"-thick wall. (Nominal values for GFCMU.)
- Titen HD® anchors may be installed into the head or bed joints.
- SDS screws may be installed through metal truss plates as approved by the truss designer, provided the requirements of ANSI/TPI 1-2014, Sections 7.5.3.4 and 8.9.2 are met (predrilling required through the plate using a 5/32" bit maximum).
- For stainless-steel LGUM models, use 3/8" x 5" and 5/8" x 6" Type 316 stainless-steel Titen HD anchors, respectively, to achieve tabulated loads.
- Fasteners: SDS screws are Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
