Gen2 units are direct replacements for original models

Changes to the housing fin design increases heat dissipation capacities, especially in the enclosed configuration of the UniModule.
Improved input to output axis design reduces vibration and improves noise and wear factors.
Use of custom designed mounting bolts allows for conduit box location directly on top of the unit.
Bolt hole patterns are re-positioned for ease of mounting.
Add-on enclosure cover kits allow for a unit to be upgraded to an enclosed unit in the field without replacing the clutch/brake. A cover plate bolts to both sides of the unit creating a completely enclosed brake package, which keeps contaminates out and wear particles in, for clean, quiet operation.
