Basic inlet plate covers are used in many Budd installations and replace 98% of all outlets. The opening is just under 1-1/2 inches, mounting screws are 4 inches apart, and the inlet fits into a 1-5/8 inch round hole in the mounting bracket. Each inlet valve can be mounted with the lid opening up or down. Note the FULL FACE inlets are the MOST DURABLE and replace oval and square styles.
All rectangle shaped valves are interchangeable. There are two metal contact points inside the hole of each inlet valve and two screws on the back side for the low voltage wire connection.
Replace 99% of older wall inlets with any of these rectangle valves. Note: these do not replace inlets activated by pressing copper or a button, or that have a 1-1/4 inch hose insertion hole.
EASY Upgrade for Budd: Consider a Low Voltage Hose to get the convenience of turning the vacuum on and off at the hose handle instead of running back to pull the hose out from the wall. All Low Voltage Hoses work with all inlets and vacuum systems. If your hose already has a handle switch you are set and it will work with these valves!
