A fast and convenient way to connect 1-1/2" and 2" vacuum hoses. The easy push-button lock keeps hoses securely together, whether going upstairs or around corners. Flash CuffsTM allow hoses to swivel, helping to eliminate tangled hoses. The tapered ends and shorter length allows the cuff to fit on the hose reel. The inside diameter is the same as the vacuum hose to prevent airflow restriction.
