Product number: HSM7
A steel, powder coated wall housing has a spring support at its top and a through hole at its lower end. A loop ended extension spring is hooked over the spring support and its remaining loop secured to a Load hanger.
Attached to the shaft of the Load hanger is an extension indicator. This has a small horizontal mark inscribed which reads up against the extension scale on the wall housing. The indicator can be moved up or down the Load hanger shaft to accurately adjust the start position of extension measurements and to cater for different length springs.
The Load hanger has a solid base onto which the set of calibrated weights supplied is suspended.
