There's a definite price advantage to the MN1100 compared to the Hoffman enclosures..list price on the MN1100, which is 5x15x11 is about $50 vs. $150 for a 10x10x4 Hoffman enclosure. But the MN1100 can't be locked--not really a consideration, I just want something that has a cover and will keep the blocks protected, I don't need max security.
