Adhaco
Multi-Point
“Blast” Fixed Latch
Type H-122

Type H-122
Horizontal Slam Multi-Point Latch



One handle controls up to five vibration-proof roller latches making the Adhaco
H-122 Multi-Point Latch the perfect solution for the large and tall Industrial doors. For the average size door, two latches normal provide the necessary sealing power. When the door closes, its inertia activates the H-122’s “slam action” to secure and seal the door panel against compression stops. This latching system is unequalled for weather-tight, sound–proof, or pressure resistant doors.
The natural pull action of the single release handle simultaneously retracts for all latch points and opens the door easily. Optional through-the=door latching is available with either a panic lever or panic bar release from the stop side. The panic lever/bar release automatically over rides optional key lock, though the door is securely locked fro m the outside, for immediate panic exit action. Strikes are adjusted to vary compression and to correct for misalignment.
Standard features include two latching points, single pull release handle, fixed strikes, corrosion-resistant high strength malleable iron castings, 1 1/2’’  precision-machined steel bolts with special flat tongue. Panic push pad release (P3) on stop side. Standard finish is U.S. Prime, other finishes available.  Standard weight 59 lbs minimum. Fasteners are socket head cap screws.
