LSC Illustration

The LSC Light Staircase Stinger Connector offers a versatile, concealed connection between the stair stringer and the carrying header or boundary joist while replacing costly framing. Field slopeable to all common stair‑stringer pitches, the LSC connector is suitable for either solid or notched stringers.

Please check the Corrosion Information to see if it is suitable for your application.

Material

Carbon Steel 1.3mm thick

Finish

ZMAX^® Galvanised

Features & Benefits

Replaces additional framing and toenailing
Suitable for most installations on 45mm x 250mm or 45mm x 300mm header/boundary joist
May be installed flush with the top of the carrying member or lower on the face
Interchangeable for left or right applications
LSCZ features a ZMAX® coating for additional corrosion protection

Installation

Use all specified fasteners
Before fastening, position the stair stringer with the LSC on the carrying member to verify where the bend should be located
Tabs on the LSC must be positioned to the inside of the stairs
The fastener that is installed into the bottom edge of the stringer must go into the second‑to‑last hole

Design Capacity is the lesser of (1) the Characteristic Capacity multiplied by the Australian Capacity Factor, or the NZ Strength Reduction Factor (φ), and applicable the k modification factors following AS 1720.1 and NZS 3603 and (2) the Serviceability Capacity which is the load at 3.2mm joint slip. Design Capacity is the minimum of test data and structural joint calculation. For Australia, the Capacity Factor (φ) is 0.85 for nails and screws for structural joints in a Category 1 application. Reduce tabulated values where other Category applications govern. For NZ, the Strength Reduction Factor (φ) is 0.80 for nails in lateral load and 0.70 for other fasteners. Duration of Load Factor (k1) is as shown. Reduce Duration of Load Factor where applicable. Capacities may not be increased. Timber species for joint design is seasoned Radiata Pine, which is Australia Joint Group JD4 per AS 1720.1 Table H2.4 and New Zealand Joint Group J5 per NZS 3603 Table 4.1. Simpson Strong-Tie stainless-steel connectors require stainless-steel fasteners. When cross-grain bending or cross-grain tension cannot be avoided in the members, mechanical reinforcement to resist such forces may be considered. A minimum distance of 19mm measured from the lowest rim-joist fastener to edge of rim joist is required. Simpson Strong-Tie SD#9 x 38 Strong-Drive SD Connector screws may be substituted for 38 x 3.75 nails to achieve published nail values if the extra screw is installed in the narrow face of stringer.
