Mounting clamp for 1&5/16"-1&3/8" diameter LCR, J.J. and similar capacitors, cadmium plated steel, made in USA. This is the clamp that fit popular 50uF+50uF/500VDC found in Marshalls, etc. Also fits the 8uF+8uF, 32uF+32uF and 100uF+100uF capacitors we also sell in our Reverb store. Mount to chassis with two machine screws, two feet. Clamping machine screw and fixing nut included. Handy Hint! Some folks who don't like the industrial look of these clamps on their hi-fi amps mount 'em underneath the chassis. That works just fine if you've got the real estate 'under the hood'.
