LevelMaster Adjustable Stair Stringer (pair)

Need a set of stairs that won't fight you on install day? LevelMaster's pre-cut adjustable stair stringers are ready to bolt down or cast into your slab, with 25mm of height adjustment built in to soak up any unevenness in the surface.

Sold as a pair, the stringers come fully hot dipped galvanised so they hold up outdoors and don't need touching up after install. Engineered to the National Construction Code and Australian Standards, they're sized for standard 50 × 250mm treads with a 175mm rise, 250mm going and a 34.75° slope.

Choose the connection that matches your footing:

• Bolt on Slab — bolts straight down onto an existing concrete pad or slab. Galvanising stays intact (no welding required), and you can fine-tune the height with the built-in 25mm adjustment.
• Inground (Cast-In) — cast into a concrete pier or footing for a permanent fix. Same engineered design, same height adjustment.

Sizes from a single tread up to 17 treads, so you can match the run to whatever subfloor height you're working with.

Features:

• Sold as a pair (matched left and right stringer)
• Hot dipped galvanised — outdoor ready, no touch-up required
• 25mm height adjustment built in
• Engineered to NCC / Australian Standards (Patent #2016206347)
• Designed for 50 × 250mm tread material
• 175mm rise, 250mm going, 34.75° slope
• Bolt-on (no welding, galvanising preserved) or Inground (cast-in)

Common applications:

• Pool and entertaining area stairs
• Granny flats and outbuildings
• Anywhere a compliant pre-engineered stringer beats site-cut timber
