I'm using plastic tubs with lids, and I went to WaMart and got the 32mm binder clips in the office supply section. These have worked out great! No drilling, no tieing anything - just clamp these on and they stay on until you unclamp them. Easy on, easy off, no more hassle - I love 'em - and no BP has made it past these clamps! No more escapees to hunt down! :banana:
