LGUM Light Face-Mount Girder and Beam Hanger for Concrete and Masonry

LGUM

On This Page

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).
  • 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).
    — 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.

LGUM/HGUM Heavy-Duty Face-Mount Beam/Girder Hangers for Concrete and GFCMU Load Table
  1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  2. Tabulated uplift loads are based on 4" minimum distance to top of wall.
  3. Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
  4. Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
  5. LGUM must be installed on minimum 6"-thick wall and HGUM on minimum 8"-thick wall. (Nominal values for GFCMU.)
  6. Titen HD® anchors may be installed into the head or bed joints.
  7. 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).
  8. For stainless-steel options, see Simpson Strong-Tie engineering letter L-C-CMUHGRSS.
  9. 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.
