overall rack dimensions height (A), width
(B) and depth (C) are important when
considering the space required for mounting on your
width (D) is the maximum width card that
can fit into the pocket.
The exposure (E)
of most racks is 3/4 to 1 inch. This is the
distance between one pocket and the next pocket.
Once the card height exceeds the pocket depth by the
amount of the rack's exposure, a taller card will
gain no further exposure. For example the numbers 1,
2 and 3 appear on the bottom card but only the
number 1 appears on the cards above it. Given a
7.00" card and a 3.875" pocket depth, 3.125" of the
bottom card is exposed (H) but only the top
1.00" of the other cards is exposed, due to the
racks exposure of 1.00". Putting cards in only every
other pocket gives double the exposure as indicated
by the top three sample cards placed.
When choosing the
pocket depth (F), be sure the
pertinent card information for retrieval will be
exposed. Ideally, your card height should equal the
pocket depth + rack exposure + 1/4". Card height
MUST exceed pocket depth by at least 1/2" or you
will have trouble removing the card once it's
Pocket thickness (G) should
be considered when using a rack for a special
purpose other than single paper items, such as
brochure storage, etc. Most time card racks have a
pocket thickness of 1/4" or less while file folder
racks have a pocket thickness up to a 1/2" or more.
Furthermore, time card rack slots are fixed, while
multi-purpose rack pockets float allowing thicker
items be placed in some pockets while limiting use
of neighboring pockets.
