HES 8000 - Manual (Page 2)

NOTE! The 8000/8300 electric strike requires that the opening be plumb and square to insure proper catch
and release of the latchbolt.
EVALUATE OPENING
Although the design of the 8000/8300 provides adjustability to
compensate for frame and door irregularities, in some cases, adjust
ing the frame and door back to industry standards is just not
an option. Here are some tips to quickly compensate for frame
twist and to determine the condition of the latch bolt.
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 8000/8300 is steepened and
may need to be corrected as shown at right.
We also recommend you check the condition of the latch bolt
prior to installing the 8000/8300. Poorly constructed, worn out or
damaged latch bolts may not slide along a ramp at any angle. To
check the condition of your latch bolt, we recommend applying
a slight force to the tip of the latch bolt (about 45 degrees to
door face). Make sure the latch bolt can be pushed up into the
door.
ACCOMMODATING 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 latch bolt 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 plac -
ing several shims under the top and bottom (stop side) of the
faceplate (Image right). This effectively increases the 8000/8300 ramp
angle and compensates for frame twist. This can also be per -
formed by placing shims under the top and bottom (bevel side)
of the latchbolt (Image below right).
