CHECKS, HOLDERS & PROPS<br />
STANDARD DOOR CHECKS<br />
Large holdback spring permits the pivot on the door bracket to pass over the center <strong>and</strong> holds the door open at 90°.<br />
A slight push releases the door to close it automatically.<br />

DOOR CHECK INSTALLATION INSTRUCTIONS<br />
With compartment door held at 90° position, mount door bracket as close to hinge centerline (X)<br />
as possible so that radius (R) swung about hinge center through pivot (A) is as short as possible.<br />
(<strong>Inc</strong>reasing (R) will increase slide travel causing an increase is spring pressure. Reducing (R) will<br />
have the inverse effect.)<br />
Keeping door at 90°, mount slide rod assembly as far away from horizontal hinge center point (Y)<br />
as possible maintaining spring in at rest position. Slide rod assembly should be mounted as close<br />
as possible to vertical hinge centerline (Z) still allowing clearance for swing rod & door bracket<br />
when door is closed.<br />
After mounting, open & close door to check clearance <strong>and</strong> spring pressure. When mounted properly,<br />
door should open with some resistance through approximately 30°~45° of travel, then travel on<br />
its own until the slide rod assembly contacts the bumper spring stopping the door in the fully open<br />
position. The same spring pressure should be present when closing the door.<br />
To increase spring tension, place door in 90° position (spring at rest). Move bracket (A) away from<br />
centerline, increase (R). To decrease spring tension move door bracket (A) toward hinge centerline,<br />
decrease (R). Please note that maintaining (Z) dimension <strong>and</strong> adjusting (R) dimension will change<br />
(Y) dimension maintaining the door at a 90° open position.<br />
