This listing is for (4) sets of 18-8 type Stainless Steel Hardware for all the Feet & Front Risers for the Collins S-Line and KWM-2 stations. (18-8 is not the size but rather the type of high grade aircraft stainless steel)
This set will fit the Collins S-Line to attach the feet! This set is offered for use with the basic S-Line set up of, transmitter, receiver, 312B-4 station console, and 516F-2 power supply, or the KWM-2, with 312B-5 station console, 516F-2 power supply, and 30L-1 amplifier. This is the same high quality 18-8 type stainless hardware the Collins company used on the S-Line and KWM-2 products.
I also offer the ORIGINAL Collins feet sets in other listings, which are to be used with this hardware set. They are the factory original feet with the washer embedded in them so no washers are with this hardware set.
