GLS Glulam Saddle Hanger


On This Page

The GLS is designed to accommodate high allowable loads for timber and glulam beams. This glulam hanger features a saddle design that eliminates the need for back-to-back hanger installation, while the Funnel Flange™ feature allows for easy installation of beams. The GLS installs with heavy N54 ring-shank nails specifically created for glulam or heavy timber.

Key Features

  • N54 ring-shank nails included
  • A cost-effective alternative to using two hangers
  • Not acceptable for nailer applications


  • 3 ga. top flange; 7 ga. stirrup


  • Simpson Strong-Tie gray paint. Hot-dip galvanized is available; specify HDG.


  • Use all specified fasteners. Verify that the header can take the required fasteners specified in the table.
  • For attaching to multi-ply headers, refer to technical bulletin Top-Flange Hanger Reductions for Multiple-Ply Headers (T-C-MPLYHEADR).
  • Flatten edge of header to match top-flange radius.
  • Bevel-cut the carried beam for skewed hangers.
  • For hangers exceeding the joist height by more than 1/2", allowable load is 50% of the table load.
  • May be used for weld-on applications. Minimum required weld is a 1/4" x 2 1/2" fillet weld at each end of the top flange; see General Instructions for the Installer, note k, for weld information. Weld-on applications produce maximum loads listed. For uplift loads, refer to technical bulletin Top-Flange Hangers Welded to Structural Steel Members (T-C-WELDUPLFT).
  • N54A nails are included. N54A nails should only be used with solid sawn, timber or glulam headers. When installing on structural composite lumber, use 1/4" x 2 1/2" Strong-Drive® SDS Heavy-Duty Connector screw in lieu of the N54A nails.
  • Loads shown are per side.
  • To order, specify H1, H2, W1, W2 and S dimensions (see illustration).


  • Hot-dip galvanized; specify HDG.
  • Seats may be skewed to a maximum of 50° and/or sloped to a maximum of 45°.
  • When seat is sloped, the maximum allowable load is 6,550 lb.
  • When seat is skewed, the maximum allowable load is 6,500 lb. The deflection at full loading may reach 1/4". For skews greater than 15°, multiply the table uplift load by 0.50.
  • For sloped and skewed seat combinations, the maximum download is 5,500 lb. per supported member. The deflection at full loading may reach 1/4". For skews greater than 15", multiply the table uplift load by 0.50".
  • Sloped or skewed seat hangers may not be installed in non-backed nailer/header installations.
  • Top flange may be sloped down to the left or right as far as 30°. Reduce allowable loads using the following reduction factor based on linear interpolation: (90–α)/90, where α is the angle measure from the horizontal. This reduction is not cumulative with other load reductions.
  • Top flange may be offset left or right for placement at the end of a header. Minimum seat width is 3 1/4". The maximum allowable load is 0.50. No uplift load is available.
  • For skewed and offset or skewed only top-flange hangers with inward or outward configuration, the maximum allowable load is the lesser of (a) 45% of the catalog load or (b) 3,500 lb.

  1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  2. Uplift loads apply only when "H" is 28" or less.
  3. For hanger heights exceeding the joist height, the allowable load is 0.50 of the table load.
  4. For SCL products made primarily from Douglas Fir or Southern Pine, use 1,640 lb. for uplift. For SPF members, use 1,115 lb. for uplift.
  5. GLS saddle hanger allowable loads are for each stirrup. Fasteners listed are total fasteners required.
  6. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
