CRL DB035CV36 Aluminum Commercial Medium-Duty Automatic Door Bottom for 36 Door

This CRL Commercial Medium-Duty Automatic Door Bottom is mechanically actuated. An internal carrier bar with a vinyl insert drops from a concealed cavity to form a tight seal between the base of the door and the threshold. It is ideal for use where carpeted interiors require the door bottom to retract when the door is opened. Supplied with a frame actuator protector plate the door bottom is field reversible for either hand of door. Actuation of the inner drop down bar only functions properly when this door bottom is installed on the door. Testing by hand before installation will only drop the back of the bar. Proper function only occurs when the back edge (near the hinge side) drops down onto the sill. Once the back of the bar makes contact the front edge will drop creating the seal. At this time adjustments can be made to the threaded hex plunger by backing out the plunger to increase the seal pressure against the sill. Most shipping weights are approximate and have not been verified. If the exact weight is needed in order to determine shipping costs and shipping costs are required in order for you to complete your order please request this prior to submitting your order by contacting CRL Customer Service.
