Whirlwind HBPR Rack Panel Back Box

A rack panel with connectors on it is open at the back, which is fine in a rack and a problem anywhere else. Ordering the matching back box turns the flanged rack panel into an enclosed unit with the wiring protected.

The part numbering is straightforward: except for R-1 and PR-1, the product number is HB plus the panel number, so the back box for a PR-2 is the HBPR-2. Select the panel size below.
