LSSJ Field-Adjustable Jack Hanger

LSSJ

The Simpson Strong-Tie® LSSJ field-adjustable jack hanger is the ideal hanger for connecting jack rafters to hip/valley members. Its simple design makes installation intuitive and quick, resulting in lower labor costs. Featuring a versatile, hinged seat, the LSSJ is easily field-adjustable to typical rafter slopes, with a max slope of 12:12. It ships prebent with a 45° skew, making it ready to place for the most typical rafter conditions, and can be field-adjusted for lesser skews. Additionally, it can be installed as a retrofit, enabling installers to first tack all the rafters into place without pausing and to then install the hanger later. The LSSJ hanger is available skewed left or skewed right.

Key Features

  • All nail holes are easily accessible on one side with a hammer or connector nail gun
  • Straightforward design makes installation quick and intuitive, saving you time and labor costs
  • Flange design allows for easy skew adjustment, from 0° to 45°
  • Accommodates roof pitches from 0:12 to 12:12
  • Swivel seat adjusts easily and provides more support to joist, allowing for higher load than fasteners alone

Material

  • 18 gauge

Finish

  • ZMAX® coating (G-185)

Installation

  • Use all specified fasteners. See General Notes.
  • Rafter end needs to be bevel cut.
  • Table and illustration show left and right skews LSSJR/L (LSSJR = skewed right; LSSJL = skewed left).

Options

The LSSJ is manufactured in left or right skews as shown in the gallery images (note the “L” or “R” in the model name). Both the LSSJL and the LSSJR version come prebent at a 45º skew for typical use but can be field-adjusted to install from 0° to 45°.

  1. Uplift loads have been increased for wind or earthquake loading with no further increases allowed; reduce where other loads govern.
  2. For LSSJ26 an extra nail in the seat at load durations (115) and (125) adds 75 lb. to 10d x 1 1/2" table downloads.
  3. Nails: 10d = 0.148" dia. x 3" long, 10d x 1 1/2 = 0.148" dia. x 1 1/2" long.
