Several of us, myself included, have been buying and sending clamps to our members who cannot find them (outside of the US) for free. Total cost for two clamps, including the clamps, padded envelope and postage is about US$5.00.
kbtd - send me a PM about this and I’ll send you some. No charge.
Those of you in the US have to try harder. They’re not that hard to find.
hardgainer12 - see if you can get to the Home Depot at 2425 Middle School Ave NW near you. They should have them.
