The lightweight and compact ERP and ER Series Spring Retractors are an economical choice when zero gravity is not required. ERP tension adjustment is accomplished with the integrated handle system. The unit includes an adjustable stopper that can be positioned to limit the stroke. Nylon-coated cables means clean operation - no greasy mess. The long cable travel of the ER model workes well for hanging push button pendant stations and similar devices.
