Digital Angle Indicators

These angle indicators display highly accurate angle, level, and tilt measurements. They come set at true 0°, but you can choose an alternate zero point with the push of a button. Another button will freeze the reading on the display. Indicators have machined leveling surfaces, a V-groove for stability on curved surfaces, and two 6-32 threaded holes for mounting.

RS-232—Angle indicator with an RS-232 computer connection can be used for ASCII output.

Digital Angle Indicators with Calibration Certificate

These angle indicators come with a calibration certificate that's traceable to NIST and includes the test measurements that confirm accuracy. The display shows highly accurate angle, level, and tilt measurements. They come set at true 0°, but you can choose an alternate zero point with the push of a button. Another button will freeze the reading on the display. Indicators have machined leveling surfaces, a V-groove for stability on curved surfaces, and two 6-32 threaded holes for mounting.

Threaded-Stud Bumpers


Style 1	Style 2

These bumpers absorb impact to protect equipment, walls, and floors from dents and scuffs. They're found everywhere from access panels to the bases of equipment. The rubber construction also stifles noise and absorbs vibration to prevent wear and tear to your machinery and nearby surfaces. No separate fasteners are needed—just twist them into a threaded hole.

Multipurpose SBR Rubber About Multipurpose SBR Rubber


Style 1	Style 2

These bumpers absorb impact well enough for most applications. However, they're not for use outdoors and break down when exposed to oil and harsh chemicals.

Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.

Load-Rated Reinforced Threaded-Stud Bumpers

Style 1

Tested to support the load of your application. These bumpers support a wide range of equipment—from a 50 lb. saw to a 5,000 lb. air compressor. They also help reduce vibration and protect whatever they’re mounted to. All have a metal base plate for added strength and a longer service life than all-rubber bumpers. No separate fasteners are needed—just twist them into a threaded hole.

Abrasion-Resistant Polyurethane Rubber with Steel Stud and Base Plate

Style 1

Our toughest rubber bumpers, they keep their shape even when knocked and scraped by metal and other abrasive materials. They're often used on industrial vehicles, conveyors, and heavy construction equipment.
