Description

The Simpson Strong-Tie LSC Adjustable Stringer Connector provides a strong and versatile connection between stair stringers and deck framing or supporting members. Designed to accommodate a wide range of stair angles, the LSC simplifies stair construction while delivering dependable structural performance.

Engineered for exterior applications, the LSC features a corrosion-resistant galvanized finish suitable for pressure-treated lumber. Its adjustable design allows the connector to adapt to various stair pitches, eliminating the need for complex field modifications. By reinforcing the stringer-to-deck connection, the LSC helps improve stability and long-term durability in deck stair systems.

Whether building new deck stairs or upgrading an existing structure, the LSC offers strength, flexibility, and installation efficiency in one reliable connector.

Key Features

  • Adjustable design accommodates a wide range of stair angles
  • Provides a secure connection between stair stringers and deck framing
  • Galvanized finish for corrosion resistance in exterior environments
  • Suitable for use with pressure-treated lumber
  • Eliminates the need for complicated angled cuts or custom brackets
  • Durable steel construction for long-term performance

Applications

  • Deck stair construction

Installation

The LSC installs at the top of the stair stringer, connecting it securely to the deck rim joist or supporting framing member. Adjust the connector to match the required stair angle, then fasten using approved fasteners per Simpson Strong-Tie installation guidelines.

The only thing the last contractor got right

I replaced the deck stairs for a friend, whose “class A contractor” had cut so many corners I was baffled the steps held as long as they did.

These fasteners were the ONLY THING THE GUY DID RIGHT. If he hadn’t put approximately 9,000 nails into each one, I could have reused them. Since he used interior stringers and put them directly on the bare ground, the nails were more structurally sound than the stringers. I was impressed at how the brackets had held up. Not a spot of rust despite 8 years of interior wood wicking moisture up to them.

I ordered 20 to be sure I had plenty … because I want to use them on my deck when I work on it next year, and maybe go into business cleaning up this dude’s messes?

(Seriously I couldn’t even reuse the composite planks the guy had put in because he’d ripped them lengthwise to make them narrower to make up for his failure to account for three dimensions. What does it actually take to get a contractor’s license??)

A new Approach to Stairs

It isn't often something really new shows up in construction, but this item is it. The way it ties stringer to ledger board is very smart and easy to apply. The question is whether it will weather well in outdoor applications. All I can say at this point is no rust yet.
