Frequently Asked Questions

Can this hanger be installed after the rafters are already in position?

Yes. The LSU4.28 is specifically designed to allow installation after the rafters are already in place, which makes it particularly convenient during framing when sequencing flexibility is needed.

What is the maximum slope or skew angle this hanger can accommodate?

The LSU4.28 can accommodate slopes up or down and skews left or right up to 45 deg., providing significant flexibility for non-standard framing applications.

Are web stiffeners required when using this hanger with I-joists?

Yes. Web stiffeners are required for all I-joist applications when using the LSU4.28. This ensures proper load transfer and structural integrity at the connection point.

How should the sloped joist be attached during installation?

The sloped joist must be attached at both ends so that the horizontal force developed by the slope is fully supported by the supporting members, ensuring the connection performs as intended under load.
