Nails may need to be driven at an angle to minimize splitting of bearing plate

For 11⁄2" thick flanges, attach with one 10d (3") box nail, minimum, each side of Red-I™ joist at bearing. Use 12d (31⁄4") box nails with 13⁄4" thick flanges. Maintain 11⁄2" minimum end distance to minimize splitting.

Traditional masonry hangers will not support construction loads ­without a minimum amount of cured masonry construction above ­hanger level. Refer to hanger manufacturer’s literature for information on the correct installation and use of masonry hangers.

When supported by a Red-I™ joist, maximum hanger capacity is approximately 2,000 lbs. Refer to hanger manufacturer’s literature for details.
