BMI Redland Cambrian Interlocking Slate and a Half 28 Heather 4702-28

Cambrain Slate and a hlaf are intended for use at right hand verges and abutments on alternate courses.

Cambrian Slates embody the beauty and character of natural slate. Made in Wales from over 60% recycled Welsh slate, Cambrian tops the range in both looks and performance and has a proven track record even on pitches as low as 15°. Whilst light in weight, Cambrian's unique three point fixing makes it suitable for even the most exposed sites.
