CLS Studwork Timber – 38 mm × 89 mm (approx. 2″ × 4″), 4.8 m
This 38 × 89 mm CLS (Canadian Lumber Standard) studwork timber, supplied in a 4.8 m length, is kiln-dried and planed with rounded edges to provide strong, stable, and easy-to-handle timber for internal framing applications. Commonly referred to as 4″ × 2″ CLS, this size is ideal for stud walls and partitions where added rigidity and longer spans are required. Manufactured to consistent dimensions, CLS timber helps minimise movement and delivers straight, accurate frameworks. The smooth, eased-edge finish improves handling safety and allows for faster, cleaner installation on site.
