Hammond 1550Z139BK Black 159 mm Square Deep Watertight Diecast Box

The 1550Z139BK is the black textured edition of the 1550Z139 deep square watertight diecast aluminum enclosure. The part page lists 6.28 in x 6.28 in x 4.02 in (160 mm x 160 mm x 102 mm) and the ordering table 6.26 in (159 mm) square with 4.02 in (102 mm) total depth. It serves engineers and installers who want a large sealed metal housing with a finished black exterior.

A tough polyester powder coat is applied outside and inside, and it is described as a lasting finish even after machining. The drawing gives inside dimensions of 149.86 mm [5.90 in] square by 97.00 mm [3.82 in] deep, and the part data allows P.C. boards up to 148.71 mm x 148.71 mm. The walls have no internal ribs.

The 0.83 in (21 mm) lid is held by four stainless steel Philips head M4 - 0.7 screws that are self-captivating: the lid holes are slightly undersized and threaded with the first installation. The screws sit outside the silicone gasket, which is rated -40°C to +150°C (-40°F to 302°F). Recommended torque is 5-7.5 lbf.in (50-75 cN.m). Blind thru-box holes support wall mounting outside the gasket ring, and a #6 self tapping ground screw fits inside.
