Fall-Arrest Anchor Points with Winch

This system provides support when lowering workers into and retrieving them from tight spaces. Use the hand-operated winch to control lifting and lowering. You supply a harness.

The system comes with an adjustable mast and a separate portable base. For fixed-base installation, use the wall-mount or floor-mount base—weld or bolt the base to a concrete or steel structure and insert the mast into the opening.

Long-Distance Sight Level Sets

Level Set

Level Set with Angle Indicator

In addition to the instrument, you get a leveling rod and tripod. Commonly seen in the hands of surveyors, sight levels rotate 360° to find horizontal level when grading for elevation.

Level set with angle indicator tilts up and down to determine incline and can be set to use only as a level. It has three leveling screws to adjust line of sight. Also called a transit level.
