Each shell shall be lined with a ribbed PVC extrusion with a retaining ridge that overlaps the shell to prevent slippage. Runner surface shall be UHMW polymer or Glass Reinforced Polymer for abrasion resistance and a low coefficient of friction. The runners and risers shall be attached at appropriate positions to properly support the carrier within the casing and to ease installation.
Stainless Steel Casing Spacers
The 8” wide or 12” wide stainless steel casing spacer shall be a two piece shell made from 14 gauge T-304 stainless steel. Each shell section shall have a flange formed with ribs for strength and with a minimum of three 5/16-inch stainless steel bolts for eight inch wide and four for twelve inch wide spacers.
