Hammond 18G2721 27x21 Galvanized Inner Panel, Fits 30x24 Enclosure

The 18G2721 is a 27 x 21 in galvanized steel inner panel made for 30 x 24 in wallmount enclosures in the 1418, 1447, PJW and PHW families. It is aimed at control panel builders, electricians and facilities teams who need a galvanized equipment-mounting panel for one of these enclosures, whether for a new build or as a spare.

Construction is unpainted galvanized steel (the series lists galvanized panels as 12 gauge and notes that some larger panels are 10 gauge). The part drawing shows a 0.10 in material dimension and formed flanges drawn at 0.75 in. Shipping weight is 19.2 lbs (8.71 kg), and the panel is packed in a box. It is RoHS and REACH compliant.

Panel length is 27.00 in (686 mm) and width is 21.00 in (533 mm), for an enclosure 30.00 in (762 mm) high by 24.00 in (610 mm) wide. The 18G2721 has 4 mounting holes of 0.50 in diameter; per the drawing, hole centres are 25.25 in along the 27.00 in length and 19.25 in along the 21.00 in width. Panel mounting hardware is not included with the panel, because it is provided with the enclosure.

The same 27 x 21 in panel size is also listed in white-finished 12 gauge steel (18P2721), brushed 316 stainless steel (18P2721S16), 5052-H32 aluminum (18A2721), fiberglass (F3024), so you can match the material to the application while keeping the same enclosure fit.
