Bic T-Rig 00cm Mast Base
This mast base from Bic fits into the bottom of your standard diameter mast and accepts a euro-pin mast foot. It works great if you do not need any extension at the bottom of your mast, just a fixed length, no extension piece. It does have pulleys and a cleat built in to it, for ease of downhauling your sail.
