This White Wall Inlet is designed to be used with the Inlet Mounting Plate #791041W when mounting in a 2 x 4 wall with drywall or plaster. A Short 90° Elbow #765506W is typically used directly behind the mounting plate. All other elbows, tees, etc. should be the sweep type so any object which is able to get through the short elbow should also pass through the others easily.   For similar products see our list of Generic Central Parts & Components.
