The Brent Mini SRC Slab Roller from AMACO is sufficiently small to fit on almost any table, but yet so sturdy that it allows for rolling slabs as big as 14" W x 15" L with a slab thickness of up to 3/4". Just like the larger SRC slab roller models, the mini is made of bent plate and steel metal pipe, making it strong and durable for years of use. This smaller slab roller is great for compact studios or workshops that have limited space. The Brent mini slab roller has a cable drive system that is patented and which produces an even and steady pressure along the bed with its opposing rollers. The roller comes with two plain shims that measure 1/8" and one shim with canvas that measures 1/4". Dimensions of the roller, when assembled, are 31" W x 26" L x 14" H.
