LSC Adjustable Stringer Connector

Key Features

• Replaces additional framing and toe-nailing.
• May be installed flush with the top of the carrying member (typically suitable for 2x10 or 2x12 header / rim board) or lower on the face (typically suitable for a 2x12 header / rim board).
• Interchangeable for left or right applications.
• LSCZ features a ZMAX^® coating for additional corrosion protection. Suitable for interior and some exterior applications. LSCSS is made from stainless steel for higher exposure environments. See Corrosion Information.

Material

• 18 gauge

Finish

• LSCZ — ZMAX coating; LSCSS — stainless steel

Installation

• Use all specified fasteners; see table.
• Before fastening, position the stair stringer with the LSC on the carrying member to verify where the bend should be located.
• The fastener that is installed into the bottom edge of the stringer must go into the second-to-last hole.
• When installed on 1 5/16" LVL or a 1 1/4" LSL stringer, additional items that will not affect the structural performance of the LSC, but should be considered, include the following:
  — LSC stringer flange will protrude 1/4" from face of stringer. As such, it is recommended the LSC be installed with the tabs positioned to the outside of the stringer.
  — 1 1/2" fasteners installed into 1 1/4" LSL stringer will protrude from the opposite side.
