The 1591FABK is a black plastic bottom flange that lets a 1591A, 1591AS, 1591XXA or 1591XXAS enclosure be fixed to a wall or shelf. It is aimed at electronics builders and installers who want a clean surface-mount option for these small plastic boxes without drilling through the enclosure itself.

The flange is molded from fire retardant ABS plastic rated UL94 V-0, with a satin texture finish. It measures 4.93 in (125 mm) long by 1.85 in (47 mm) wide, and the part lists an IP54 rating. One flange is included.

Installation is straightforward:

• Glue the enclosure to the flange with standard ABS cement (not included).
• The flange ends are raised on one side to help position the enclosure while the cement sets.
• Fasten the flange to the wall or shelf through its four molded countersunk holes.
• Alternatively, use the oval hole in each side to strap or hang the unit with tie wraps.

The 1591FABK is RoHS and REACH compliant, ships shrink wrapped at 0.04 lbs (0.02 kg) and carries UPC 623980135939. A light gray version is available as 1591FAGY.
