The G.R.A.S. RA0052 is for use with G.R.A.S. couplers and artificial ears. It has an adjustable spring-loaded arm to exert a variable force on the test object.
The design of RA0052 enables mounting of two additional springs, for high-tension setups. These two springs are delivered with the RA0052.
For previous versions of RA0052, designed for two springs only, the G.R.A.S. RA0196 High-tension kit is available. This kit, including four springs, is offered for replacement of the top of RA0052.
