Handles

Damper Control Arms

Connect ball swivels and damper linkages to an actuating motor to control ventilation dampers.

Tapered Lever Handles

Use these handles as grips on hand wheels and cranks to operate machinery.

Miniature Tapered Lever Handles

Also known as finger handles, these are less than 1" long. Use them as tiny grips on small hand wheels and cranks to operate machinery.

Metal-Detectable Tapered Lever Handles

These handles are often used as grips on hand wheels or cranks to operate machinery around food processing lines without the risk of contaminating the food. Install them on a threaded stud.

Push-On Tapered Lever Handles

Press fit one of these handles into a shaft, rod, or hand wheel to operate machinery.

Crank Handles

Unthreaded Through-Hole Crank Handles

Round long shafts can pass through these handles for mounting versatility. Create custom threads or drill a hole in the side of the hub to secure with a set screw. Often used on cross-slide tables, these crank handles provide leverage to maximize force for turning and tightening.

Machinable-Hub Crank Handles

Mill specific holes or keyways in the hub to meet your specifications or weld in place. Often used on cross-slide tables, these crank handles provide leverage to maximize force for turning and tightening.

Balanced Machinable-Hub Crank Handles

Balanced weight distribution prevents unintentional handle movement, even in high-vibration applications. Mill specific holes or keyways in the hub to meet your specifications or weld in place. Often used on cross-slide tables, these crank handles provide leverage to maximize force for turning and tightening.

Unthreaded Square Through-Hole Crank Handles

Square long shafts can pass through these handles for mounting versatility. Drill a hole in the side of the hub to secure with a set screw. These crank handles provide leverage to maximize force for turning and tightening. They are often used on cross-slide tables.

Adjustable-Position Crank Handles

Use these crank handles for applications that involve frequent machinery adjustments. They provide leverage to maximize force for turning and tightening.
