    Know Your Stainless-Steel Enclosure: Quarter Turn Latch

    Quarter turn latch enclosures. Steeline Enclosure Solutions knows that picking out the right stainless-steel enclosure can be a daunting task. Factors to consider are what materials will the enclosure protect, from what environments will the enclosure protect the contents, what type of enclosure material is ideal, how many doors on the enclosure are ideal, and even what type of latch best serves the needs of the application. In this article we’ll look at the quarter turn latch, its pros and cons, and which Steeline products offer Quarter Turn Latch Enclosures

    What Is a Latch, Anyway?

    Wikipedia defines latch as a type of mechanical fastener that joins two (or more) objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface.

    When considering which electrical enclosure will best meet your needs, one of the factors to consider is how often the enclosure will need to be opened and at what ease can the enclosure be opened. The value of the enclosure’s contents and the degree of security desired will impact what type of latch is required.

    Why Are Quarter-turn Latches Common in Electrical Enclosures?

    Steeline Enclosure Solutions uses basic compression quarter turn latch inserts that are flush slotted inserts. All electrical enclosure applications will require a degree of protection by either the IP or NEMA classification. The sealing or gasket in the enclosure must be compressed to a certain level to conform to the required IP or NEMA classification. Consequently, a compression latch is required.
