Spurs and Miters
Installation, operation, and maintenance manual.
Spur and miter gears are used in applications requiring a nonself-locking mechanical advantage or a change in input drive orientation.
Both devices can be used as add-on features to our worm and bevel gears or purchased as stand-alone products.

Table footnotes
* Model numbers that end in A are stand-alone models that are not made to close couple to existing products. These models also have input (handwheel) shaft and output shaft connections. Models that do not end in "A" are designed to close couple to Dynatorque 90™ quarter-turn worm gear operators. These models have input (handwheel) shaft connections and use the input shaft from the primary operator for their output shaft connections. Models that do not end in "A" are offered as component parts that are assembled to primary operators.
** Bolt patterns are offset to match standard spur and miter attachment patterns on faced operators.
