ASSA ABLOY A121 Mounting Plate with Bushing for Tandem DC300 Door Closers

Product Overview

The A121 mounting plate with bushing is intended for use with tandem configurations of Assa Abloy DC300 door closers. Typically installed in commercial and public sector buildings, it provides a dedicated interface for attaching two DC300 closers on a single door where tandem operation is required by building codes or door size.

Unlike standard mounting plates, the A121 features an integrated bushing specifically designed to support synchronized function and weight distribution for tandem DC300 installations. This eliminates procurement errors linked to incompatible hardware and streamlines installation on doors with high operational demands. It is particularly suited for professional door hardware installers and contract projects requiring compliance with tandem closer specifications.
