SMOOTH GEARING SYSTEM: BluBird's metal retractable hose reel has a smooth auto-rewind 12 point locking ratchet gear system allowing you to lock at various lengths. LIGHTEST, STRONGEST, MOST FLEXIBLE: BluBird's 100% rubber air hose is 40% lighter than standard industry hoses and as light a hybrid or PVC hose. It is stronger than the best of rubber hoses. UNMATCHED COLD WEATHER FLEXIBILITY: Remains as flexible at -50F as the best hybrids at 0F. Perfectly usable. Doesn’t become a noodle up until 200F. NEVER COIL YOUR HOSE AGAIN: Fully retractable, four rollers to reduce hose wear, horizontal or vertical wall mount options, an adjustable guide arm, includes 50 ft 1/2 inch and 3' lead-in hose.
