Brixon 4HCI #4 Latch Body, Handle & Strike, Cast Iron
The Brixon 4HCI #4 Latch Body, Handle & Strike is available in iron or aluminum cast housings. Pin through cam is stainless steel in all #4 latches, with other stainless steel parts optional. The #4 latches have the most variations and handle options and together with the new Model 94 are the largest and most powerful FM approved explosion venting latches made.
This industrial oven door latch is often used as a explosion relief latch or as a spring relief latch on industrial oven doors. Brixon is a great choice for door latches because they offer the widest pressure release range of any Factory Mutual (FM) approved explosion venting latch manufacturer, from as low as .01 PSI to pressure in excess of 3,000 pounds per door (using multiple latches). In addition to reliability and convenience, Brixon latches are designed to allow for installation from flush to well over 1 " offsets.
Release Force Range: Adjustable: 58-285 lbs. (26.3-129.3 kg)
Handle Options: The #4 iron latch is available with no handle or two different types of handles. The standard handle
is identical in appearance and operation to the #3 handle and is suitable for lever assisted opening
of doors with only one latch. Doors requiring multiple latches may be opened with our special
heavy-duty handle which allows lever assisted opening of several latches with no connecting
linkage. The heavy-duty handle may be used as part of a latch (model #4 HD-PS iron), or it may be
mounted separately (model 410 handle). If connecting several latches is desirable or cost
effective, special model #4P-L iron latches may be linked to a single #4H-L iron latch.
