LT Composite Wood Products Hanger
This product only available in Canada
A dedicated range of Top Flange I-joist hangers meeting the unique needs of I-joists while offering superior performance and ease of installation.
The LT series of top flange hangers is designed for use with wood I-joists. Installation is fast and easy. The hanger's top flange simplifies placement and the side flanges laterally support the I-joist top flange eliminating the need for web stiffeners. Securing the carried I- joist is simple with only one screw required into the bottom flange through the seat of the hanger for joists less than 3" wide and two screws for joists 3" and wider.
Material: 18 gauge
Finish: Galvanized
Installation:
- Use all specified fasteners. Verify that the header can take the required fasteners specified in the table.
- LT's face flange triangle hole (optional) secures hanger against header and can be used to provide increased uplift capacity. See optional nailing table.
Factored Resistances:
- The LT hanger has locations for optional nails if additional uplift is needed. Optional uplift nailing requires the addition of properly-secured web stiffeners. See the resistance tables for minimum required fasteners and factored uplift resistances.
Options:
- Because these hangers are fully die-formed, they cannot be modified. However these models will normally accommodate a skew of up to 5°.
- Product tests show a 10% reduction in ultimate hanger strength when the joist is sloped to 1/2:12 when used with these hangers. Local crushing of the bottom flange or excessive deflection may be limiting; check with joist manufacturer for specific limitations on bearing of this type.

This table indicates the maximum factored normal resistances for LT hangers used on wood nailers. The header nail type must be substituted for those listed in other tables.
- Maximum factored uplift resistance (KD=1.15) for nailer applications is the lesser of the value shown in the "Various Header Applications" table or 385 lbs. (1.71kN).
- Factored resistances have been increased 15% for wind or earthquake loading with no further increase allowed. Reduce according to the code for normal loading criteria such as in cantilever construction.
- Web stiffeners are required on I-joist for additional nailing.
- When I-joist is used as header, all nails must be 10dx1 1/2.
- Resistances may not be increased for short-term loading.
- Uplift resistances are based on D.Fir-L, and have been increased 15% for wind or earthquake loading with no further increase allowed. Divide by 1.15 for normal loading criteria like cantilever construction. For S-P-F use 0.71 x resistance.
- Applies to LVL headers made primarily from Douglas Fir or Southern Pine. For LVL made primarily from Spruce Pine Fir or similar less dense veneers, use the values found in the S-P-F column.
- For flanges less than 1 1/2" thick multiply table values by a factor of 0.85.
- Minimum solid header thickness to achieve LT table loads is 1 3/4".
- Structural composite lumber is laminated veneer lumber, Parallam® PSL and TimberStrand® LSL.
- Joists 3" in width and greater require 2-#8x1 1/4" wood screws
