Brass stem band. 1/2 inch wide by 1/8 thick half oval. Not pre-drilled. Sold in either 6 ft. or full length of 12 ft. only. This product is commonly found on older style wood canvas canoes or on keels of row boats. NOTE: Single 6ft. pieces are shipped coiled. So if you order 2 - 6 footers, it may be one piece of 12 ft. coiled. This is due the high cost of shipping long items. If you wish it shipped straight, then surcharges will apply and we will contact you for extra charges before shipping.
