Features and Benefits:

• Features a 1.375” highly flexible commercial grade crushproof vacuum hose with smooth interior for superior airflow. Unlike many standard central vacuum hoses that have a 1.25” inner diameter the larger diameter of the 91453 delivers up to 15% higher airflow to ensure superior cleaning.
• Features an Italian made 16” metal curved end with a unique 360 degree swivel feature that helps preserve hose life and prevents the hose from putting stress on wrists and forearms during vacuuming.
• The curved end has a multiple position air relief for the airflow control necessary when cleaning surfaces that want to seal off the vacuum like upholstery and draperies.
• The 7” chrome steel wall valve end is designed to be universal to industry standard wall valves featuring a tapered end for easy insertion and steps over its length to ensure it is compatible with valves both current and past.

Compares very favorably with the Broan Nutone CH235 and Beam Basic straight air hoses.
