Model #4 Latches
The #4 latch is available in aluminum cast housings. Pin through cam is stainless steel, with other stainless steel parts optional. The #4 latch has 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. Please refer to the 84 steel latch or the 94 stainless steel latch for other models with the same pressure release range.

RELEASE FORCE Adjustable: 58-285 lbs. (26.3 -129.3 kg)
HANDLE OPTIONS The #4 aluminum latch is available with or without handle. The standard handle is identica in appearance and operation to the #3 handle and is suitable for lever assisted opening of doors with only one latch. If connecting several latches is desirable or cost effective, special model #4P-L aluminum latches may be linked to a single #4H-L aluminum 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 #84 HD-PS aluminum), or it may be mounted seperately.
