Product Questions

This part in the pic shows a part number in the casting that reads 001010405 - is this the actual part that is listed? Thx

Hello Mike,

We received a bulk purchase of these swivels, and the photos show one that was basically just picked at random. Whether every single swivel has that 001010405 number, I cannot say. Since they are stored at a fulfilment location, we cannot get additional info on them. We CAN tell you they are all 278A03PM-1 swivels if that helps.
