Sierra horizontal configuration drawings provide mounting specifications for the mid-capacity Sierra motor system handling up to 1,500 pounds and 67 ft-lbs of torque in horizontal I-beam installations. These professional shop drawings include mounting dimensions, clearance requirements, and installation specifications designed for residential and light commercial applications where overhead space is limited. 

The Sierra's horizontal configuration fits within steel I-beam flange spaces while maintaining full capacity for four to five panel systems. Architects and contractors specify this configuration for modern residential glass wall systems, townhome projects, and light commercial installations requiring concealed motor placement with limited ceiling height. 

The Sierra horizontal mount provides an ideal balance between capacity and compact footprint for mid-range door automation projects.
