DC USA Approved Assa Abloy 8300 Fire Rated No Frame Cutting Electric Strike For Cylindrical Locks With Latchbolts Up To 5/8" Throw
The DC USA Approved 8300 series is a fire rated, compact, high performance electric strike featuring a unique concealed design for use with cylindrical locksets. No cutting on the frame is required. Simply remove the existing strike plate, adjust the vertical alignment feature to the latchbolt centerline and install. Its strength is derived from a unique keeper pin locking design, enabling the 8300 to exceed the ratings of the frame, door and locking hardware. This unique electric strike is easy to install and complies with NFPA 80-07 guidelines for retrofit into fire-rated frames. The DC USA Approved 8300 accommodates latchbolts up to 5/8" throw.

Reduce your install time by evaluating your opening
The DC USA Approved 8000/8300 Electric Strikes can be adjusted to compensate for frame and door irregularities. Sometimes, adjusting the frame and door back to industry standards is not an option. Here are some tips to quickly compensate for frame twist and determine the condition of the latchbolt.
Measure Frame Twist
One way to measure frame twist is to place a carpenter square on the stop and the face of the door. If the angle is less than 90 degrees, the 45 degree ramp angle of the DC USA Approved 8000/8300 is steepened and may need to be corrected as shown (Figure 1).
We recommend you check the condition of the latchbolt prior to installing the 8000/8300. Poorly constructed, worn out or damaged latchbolts may not slide along a ramp at any angle. To check the condition of your latchbolt, we recommend applying a slight force to the tip of the latchbolt (about 45 degrees to the door face). Make sure the latchbolt can be pushed up into the door.
Compensate for Frame Twist
When a frame is twisted, the relationship between the face of a closed door and of the inside face of the frame (i.e., rabbet) may not meet the 90 degree industry standard. Untrue frames and doors impact latchbolt wear and the force required to exit, so we recommend you ensure that the angle is between 90–95 degrees.
If manipulating the frame is not possible, we recommend placing several shims included under the top and bottom (stop side) of the faceplate (Figure 2). This effectively increases the 8000/8300 ramp angle and compensates for frame twist. You can also compensate for frame twist by placing shims under the top and bottom (bevel side) of the latchbolt (Figure 3).
