The SOMMER US3123 Side Mount Kit is a genuine OEM accessory designed to provide an alternate mounting option for SOMMER garage door openers. Instead of suspending the opener and rail from overhead supports, this kit enables a side-wall installation to clear obstructions or accommodate low headroom layouts in residential garages or similar applications. It serves as a practical replacement part or upgrade for situations where standard ceiling mounting is not feasible, helping maintain proper opener alignment and smooth operation of SOMMER Direct Drive systems.
This kit is intended for SOMMER operators listed by the manufacturer and is typically associated with North American Direct Drive models. Always consult the opener’s official documentation or SOMMER’s compatibility chart for model confirmation before purchase. Installation involves anchoring to a structurally sound surface and ensuring the rail remains straight and parallel to the door track; the opener’s electrical and programming procedures remain unchanged. For safety, follow UL 325 requirements and the opener manual, including correct placement of photo-eye sensors and verification of door balance and travel limits. This is not a stand-alone operator; it is mounting hardware engineered specifically for SOMMER-branded openers noted by the manufacturer as compatible.
