These are the original rescue cans developed by Bob Burnside-L.A. county chief over 30 years ago. Compare our high quality cans before purchasing weaker imitations. We use only the strongest cross-linked polyethylene - the competition doesn’t. Molded, pebble-grained hand grips to reduce slippage. Our cans have the thickest walls for strength and heavy duty 2" nylon strap and 10’ of 11/32" line.
