We have been asked for some kind of display rack for years, I'm happy to say that Ted Hume down in Texas as finally come up with something that is useful, affordable and attractive. Each is correctly sized both for width and body thickness, and the rules can be displayed very attractively on a desk, shelf or wall unit. Holds 12 rules. B. Simplex and Mannheim rules. Holds 8 rules.
Slots are wider to accommodate thicker rules.
C. Duplex rules. Holds 13 rules closely spaced. Holds 7 rules in wider spaced formation, where all of each rule is visible when in the rack. Very nice appearance. Display and storage in a minimum of space, with all rules visible.
