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

LT Typical LT Installation LT Installation
Toe Nailing
Toe nailing causes squeaks and improper hanger installations. Do not toe nail I-joists before installing top flange or face mount hangers.

top Wood I-Joists:

Sloped Joists
For sloped joists up to 1/4:12 there is no reduction. For slopes greater than 1/4:12 see individual product pages or refer to technical bulletin T-SLOPEJST.

Multiple Joists
Multiple joists should be adequately connected together to act as one unit.

Fasteners
Use the correct nails. Wood may split if the nails are too large. Hanger nails should not exceed 10d x 1 1/2" (0.148 dia.). Nails into web stiffeners should not exceed 16d commons (0.162 dia.).

Eccentrically-Loaded I-Joists
Supporting a top flange hanger may require bottom flange restraining straps, blocking or directly-applied ceiling systems to prevent rotation at the hanger location.

Attach backer block with 10-10d nails. solid-sawn backer blocks may split if a row of closely-spaced nails goes along the wood grain.

For I-joist to I-joist connections, the nails should extend through backer block and web. Refer to manufacturer's literature for other attachment details.

When supporting one I-joist from another, install backer blocks to the carrying I-joist with 10-10d nails. Check with the joist manufacturer to see if backer blocks are required on both sides.
     
top Nailer Table:

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.

Table
  1. 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).

top Optional Nailing for Increased Uplift:
Table
  1. 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.
  2. Web stiffeners are required on I-joist for additional nailing.

top LT Series With Various Header Applications:
Table
  1. When I-joist is used as header, all nails must be 10dx1 1/2.
  2. Resistances may not be increased for short-term loading.
  3. 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.
  4. 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.
  5. For flanges less than 1 1/2" thick multiply table values by a factor of 0.85.
  6. Minimum solid header thickness to achieve LT table loads is 1 3/4".
  7. Structural composite lumber is laminated veneer lumber, Parallam® PSL and TimberStrand® LSL.
  8. Joists 3" in width and greater require 2-#8x1 1/4" wood screws
