Hammond 18P3321S16 33 x 21 In 316 Stainless Steel Inner Panel

The 18P3321S16 is a 33 x 21 in brushed 316 stainless steel inner panel for 36 x 24 in enclosures, part of Hammond's 18P Series of inner panels for 1418, 1447, PJW and PHW wallmount enclosures. It gives panel builders and OEM engineers specifying stainless steel builds a dedicated surface for mounting components inside the enclosure.

The S16 suffix marks the stainless steel build: the series specifications state that stainless steel panels are 12 gauge and brushed 316 SS. Larger panels in the series have two or four formed flanges, and the drawing for this part shows a 0.75 in formed depth. Note that the stainless version ships at 24 lbs (10.89 kg), compared with 22 lbs for the white steel 18P3321 of the same size.

The panel measures 33.00 in (838 mm) long by 21.00 in (533 mm) wide and is listed for enclosures 36.00 in (914 mm) high by 24.00 in (610 mm) wide. Hammond's drawing shows 6 mounting holes of 0.50 in diameter, spaced two 15.63 in pitches along the 33.00 in length; 19.25 in across the width, and a 0.10 in material thickness. Shipping weight is 24 lbs (10.89 kg).

Panel mounting hardware is not included; the series notes it is provided with the enclosure. The 18P3321S16 is RoHS and REACH compliant and ships in a box. The same panel size is also listed as 18P3321 (steel), 18G3321 (galvanized steel), 18A3321 (aluminum).
