A wall buck is a steel in-wall insert that provides the frame and support structure for mounting a trash chute hopper door into the wall opening.
Do wall bucks differ by door model?
Yes. Wall bucks are sized to match specific hopper door models, such as Sargent HD5 or HD8 series doors, so it's important to confirm the model before ordering.
Is a wall sleeve the same as a wall buck?
A wall sleeve serves a similar purpose but is designed for universal stainless steel trash chute doors rather than a specific cast iron hopper door model.
