In architectural construction, even the most carefully built substrates are rarely perfectly flat, level, or plumb. Minor irregularities in walls and ceilings are common across projects of every scale, and these inconsistencies can complicate accurate panel installation.
To help installers overcome these real‑world conditions with greater speed and precision, Fastmount has introduced two SLX Shims – a simple, purpose‑built solution for achieving reliable leveling with the SLX range.

The new shims are engineered to integrate seamlessly with architectural clips from the SLX range – the SLX-F40R, SLX-F1.5R and their fire rated variants.
To accommodate a range of tolerances encountered across global construction markets, SLX Precision Shims are available in:
- 1/8″ (3.2 mm)
- 3/64″ (1.2 mm)
Installers can use a single shim or combine sizes to achieve the exact adjustment required.
SLX Shims are now available through Fastmount distributors worldwide, or for US customers at shop.fastmount.com.
For technical details you can access data sheet sand layout guides from our Technical Resource Library.
