After making some slight alterations to our Killion line, we are now able to produce 1.5" to 1.75" diameter rodstock from TOPAS 8007 and TOPAS 5013. These can be made available in 1 foot increments. TOPAS 6013 is available in 1.5" diameter. Other grades will be developed as our modifications allow. Previous inventories of rodstock from other grades are still available. Inquire if interested.
