Our B Series Tubular Motor offers the flexibility of either Star Bracket or Flat Fixing Plate options and the unique design of the motorhead with the 4 fixing lugs enables the installer to attach the fixing plate without the need for removing and replacing the head bolts.
The plate simply slides over the lugs and is locked into place with a single screw. If you want a Star Bracket fixing, that's not a problem either as the motorhead is pre-machined to accept the supplied boss and plate for locating onto the star bracket.
The other feature of this motor is the Limit collar and Drive Adaptor. The adaptor is manufactured as either 4"x 16swg or 4"x 9swg sizes but with a built-in 70mm Octagonal adaptor. Simply remove the outer 4" casing and the motor converts to a 70mm Octagonal drive. The limit collar is also 70mm Octagonal with 4" Crown. Just remove the Crown for 70mm Octagonal Tube installation.
The range consists of 110nm, 120nm and 150nm Tube Motors with a body size of 59mm, with Manual Override and is supplied with Adaptors, Limit Setting Tool, Rigid Eye and Flat Slide on Fixing Plate & Star Bracket. All B Series Motor Heads are identical, and have speeds of 12rpm.
