LGUM/HGUM Heavy-Duty Face-Mount Beam/Girder Hangers for Concrete and GFCMU

LGUM/HGUM

On This Page

Face-Mount Masonry Hangers

This product's information may differ depending on the category of use. You are currently viewing details related to Face-Mount Masonry Hangers. You can also view product information related to the category: Masonry Hangers for Plated Truss

High-capacity beam or girder hangers for concrete or masonry applications. Installation is made easier using Strong-Drive® SDS Heavy-Duty Connector screws (provided) into the wood member and Titen HD® anchors (provided) into the masonry.

Material

  • See table

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 (i.e. 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.
  • Carbon-steel Titen HD is not recommended for exposed exterior applications.
  • Provide moisture barrier between beam and wall per jurisdictional requirements.

Options

  • For HGUM only — Other seat widths and hanger heights available. Order as "X" version.
  • HGUM available with one flange concealed. See tables for reduced load at end of wall and outside corner.
  • LGUM/HGUM available in skews up to 45°. See Hanger Options.
  • For stainless-steel options see Simpson Strong-Tie engineering letter L-C-CMUHGRSS.

Load Tables

    For stainless-steel fasteners, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.

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. For HGUM installations with 15" minimum distance to top of wall, uplift loads are 6,180 lb. for GFCMU and 6,585 for concrete.
  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.
