Canadian Product: LF I-Joist Hanger

This product only available in Canada

The LF series is ideal for applications not requiring web stiffeners. The economical LF series comes with a height designed to support the top chord of the I-Joist. This feature reduces installation time as well as material costs.

Material: 18 gauge

Finish: Galvanized

Uplift Resistances:

Models have optional triangle joist nail holes for additional uplift. Properly attached web stiffeners are required.
LF - add two additional 10dx 1/2" joist nails for a total factored uplift resistance of 540 lbs D.Fir-L and 390 lbs S-P-F (K_D=1.15).

Installation:

Use all specified fasteners. Verify that the header can take the required fasteners specified in the table.
Web stiffeners are not required with I-joists when the joist top flange is laterally supported by the sides of the hanger. I-joist manufacturers may require web stiffeners.

Options:

These hangers cannot be modified. However, these models will normally accommodate a skew of up to 5°. For a sloping joist to 1/2 :12, tests show a 10% reduction in ultimate hanger strength. Local crushing of the bottom flange or excessive deflection may be limiting; check with joist manufacturer for specific limitations on bearing of this type.

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 into flanges should not exceed 10d common (0.148 dia.), no longer than 1 1/2". 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.
