The EM22 have been designed and engineered for use with various Pelco enclosures. The EM22 mounts to a wall or other vertical surface and features a cast-aluminum wall arm which minimizes undesired horizontal movement. Allowing 360-degree horizontal movement. Fabricated from corrosion-resistant aluminum, each unit will support loads up to 40lb (18.14kg). The EM22 can be adapted for pole mount applications when used with the PA100 mount adapter.
