One 24″ Rociprolap lap plate only. This cast iron lap plate is 24″ across and has cavities of 3/16″ x 1/2″ to help distribute the grit. Weight of the 24″ lap plate/pan is approximately 75 pounds. It is capable of holding up to 174 lbs. The units last for a very long time, but at some point you may need to replace your worn lap plate with a new one. Use the worn lap plate for the polishing lap plate or some regrind the cavities. (We used our Rociprolaps off and on for approximate 15 years and never needed regrinding the cavities.) Shipping weight 98 lbs. Inquire to Covington Engineering Corp. for a re-dimpling of the cavities of the 24″ unit. Dimensions: 32″ x 32″ x 9″, stock CRL124. The Rociprolap machine is manufactured by Covington Engineering Corp. Covington Products are shipped from Meridian, ID.
