AMACO Slab Rollers - Brent Mini SRC. Portable, yet extremely sturdy, this slab roller is compact enough to fit on a table while rolling out slabs up to 14" W x 15" L. Maximum slab thickness is 3/4". The Mini SRC is ideal for taking to workshops or for studios with limited space. It is constructed of steel pipe and bent plate like the SRC so it will last for many years. The patented cable drive system with opposing rollers produces even pressure along the bed. It includes one 1/4" shim with canvas and two 1/8" plain shims. Assembled dimensions: 31"W x 26"L x 14"H.
