At 100 x 50 x 24 mm, the 1551WYBK is the longest and deepest size in the 1551W watertight miniature enclosure series. This black version has no flanges and suits designers who need a slim, sealed housing for a longer, narrow circuit board, indoors or out.

The body is 100 mm (3.94 in) long, 50 mm (1.97 in) wide and 24 mm (0.94 in) deep including the lid, a little deeper than the 22 mm 1551W sizes. Molded-in PC board standoffs accept #2 self-tapping screws and a board up to 94.5 mm long by 44.5 mm wide. Recommended torque is 21-28 ozf.in (15-20 cN.m) on #2 internal screws and 71-100 ozf.in (50-70 cN.m) on the #4 cover screws.
The purchased assembly includes box, lid, gasket and four #4 plastite self-tapping cover screws. Alternatives in the same size are 1551WYGY (other colour) and 1551WYFLBK (with flanges); replacement gaskets are 1551WYGASKET (2-pack). RoHS and REACH compliant, shrink wrapped, 0.11 lbs (0.05 kg).
