®	FACE MOUNT HANGERS LU/LUP/U/HU STANDARD JOIST HANGERS

Model configurations may differ from those shown. Some HU models do not have triangle holes. Consult factory

See Hanger tables on pages 36 to 39. See Hanger Options on pages 73 to 78 for hanger modifications, which may result in reduced loads.

LU--Value engineered for strength and economy! Just a tap of the hammer at each speed prong secures the LU for easy nailing. Precision-formed--engineered for installation ease and design value.

LUP--Precision-formed and engineered for fast installation and maximum loads. Speed prongs are curved steel for extra strength. One hit positions the hanger for header nailing, eliminating joist nailing and the need for special short nails.

U--The standard U hanger provides flexibility of joist to header installation. Some models have speed prongs for fast installation. Versatile fastener selection with tested allowable loads.

HU--Most models have triangle and round holes. To achieve maximum loads, fill both round and triangle holes with common nails. These heavy-duty connectors are designed for schools and other structures requiring additional strength, longevity and safety factors.

MATERIAL: See tables on pages 36 to 39.

FINISH: Galvanized

INSTALLATION:

• Use all specified fasteners. See General Notes.
• LUP--Speed prongs provide instant location of the hanger onto the carrying beam and nailless securing of the joist onto the hanger. If a joist prong is deflected or bent on a knot, nail a 10dx1-1/2" or equal through that slot. On cantilevered joists, use a 10dx1-1/2" nail at each prong in addition to the prongs.
• HU--can be installed filling round holes only, or filling round and triangle holes for maximum values. See tables.

OPTIONS:

• See Hanger Options on page 75, for sloped and/or skewed U/HU models, and HUC (concealed flange) models.
• HU only--rough beam sizes available by special order.
• See also LUS and HUS series.

JOIST SHEAR LOADS

The maximum capacity of a horizontal joist or rafter may be limited by the maximum horizontal shear capacity. This table gives the capacity for common sizes.

1. DFL= Doug Fir-Larch; SPF= Spruce-Pine-Fir.
2. FV=95 psi for DFL, 70 psi for SPF.
3. The 115 and 125 loads are 115% and 125% of the 100% column, according to the code for short-term loading.
