The WORKSHOP Locking Hose features a 1-7/8 inch diameter, which effectively reduces clogging when compared to the standard shop vac hoses with a 1-1/4-inch diameter. The 1-7/8” diameter also provides a great blend of maneuverability and airflow. The locking tab keeps the shop vacuum hose connected, but detaches easily when done. Enjoy the ideal balance of maneuverability and airflow with the 1-7/8-inch diameter.
