I've been through several iterations on these, trying to make them more functional and cheaper every time. I think I've got them to be about as "high speed/low drag" as I can. They aren't as pretty as the other versions, but they're about half the price, so I'm gonna call it a win. The magnets are ~5/8" in diameter, and the stem handles are ~1" long. They don't come with the spacer pins as most folks seem not to want them, but the pin kits can be bought for $3.25 each if you want to add them on later. If I can come up with a cheaper way to make the spacer kits, that price will come down some, but right now it's kinda labor intensive, so that's what I've gotta have for them. Alliance Member Prices: $3.75 each $35 for ten (10) $85 for twenty five (25) Shipping for up to and including 25 clamps is a flat rate of $9. Over 25 clamps is a flat rate of $17. The margin on these parts is already razor thin, so these prices already include the Alliance Discount. Non-Alliance Members add 15%. I'm gonna have to be a bitch and exempt them from the big sale. I just can't afford to sell them at a discount, 'cause the margin is already so thin. I'd basically be paying you guys to buy them. I like you all, but maybe not that much. I will try to keep these in stock all the time from now on. That is all.
