Ceiling Requirements
• To allow installation of the stationary rail cross-members, clearance is required
between the ends of the stationary rails and the walls.
• It is recommended that sprinkler heads not be placed between the stationary rails.
All sprinkler heads should be mounted so they do not extend downward more than
1/4" (6.35 mm) from the ceiling while in the ’resting’ position.
• In addition, there should not be anything mounted in the ceiling (i.e. lights, A/C
returns, etc) between the stationary rails. This is because the OTS longitudinal drive
belt assembly is located on the movable bridge, approximately centered between
the two stationary rails, and may come into contact with those ceiling-mounted items
during normal use.
Complete details of room dimensions must be known when planning an installation. Work with the architect or building
engineer and obtain approval from the customer before proceeding with the layout plan.
Methods of support that will permit attachment to structural steel or through bolts in concrete construction should be
favored. Do not use anchors in direct tension.
Each rail has mounting holes on 660.4 mm (26 in) centers with the first hole located 55 mm (2 in) from the rail mount
end. The last hole is located either 55 mm (2 in) from the other end with a variable space of less than 660.4 mm between
it and the second last hole.
