Hammond Mfg. - Watertight - Thick Wall - Diecast Aluminum (1550Z Series)

Very economical - thick wall - diecast aluminum - watertight electronic instrument enclosure.
Rugged, diecast aluminum alloy (tough - yet easy to machine),
Two piece “tongue & groove” construction for protection against access of dust and water.
Ideal for repetitive opening and closing.
Easy to wall mount using "through box - blind hole" construction (on all sizes except 1550Z102 & 1550Z120). Access to blind holes is outside of gasket ring for superior protection (see photo features below).
Unpainted version is vibra finished for a smooth surface with no sharp edges.
Painted version is painted with tough polyester powder paint for a lasting finish, even after machining. Paint is applied to the entire enclosure (inside & out).
Lid secured with either two, four or six (count varies with size) stainless steel, Philips head, counter sunk, machine screws - into factory tapped holes (sizes vary - refer to PDF drawings for details).
Lid screws are outside the gasket protection area to eliminate the need for "O" rings on the screws.
On six sizes (the 1550Z107, 1550Z108, 1550Z116, 1550Z117, 1550Z137 & 1550Z139) lid screws are self captivating. The lid holes are slightly undersized & threaded with the first installation of the self tapping - lid screws (see photo features below). Enclosure holes are pre-tapped.
Designed to meet IP66 (NEMA 1, 4, 4X, 12 & 13 ratings) - gasket is pre-formed, one-piece - silicone rubber. Easy installation into lid groove.
No internal ribs for easy installation of connectors without interference or additional milling.
