Cluster Box Units and All-Weather Parcel Lockers

During Mailbox Improvement Week, postmasters and managers or their designees must review all cluster box units (CBUs), neighborhood delivery and collection box units (NDCBUs), and outdoor parcel lockers (OPLs) in their delivery areas to identify any hazards or irregularities, and they must record the results of the review.

Note: NDCBUs are not approved for use in new delivery or as replacement units for existing NDCBUs — even when privately purchased. Postal Service officials must not install Arrow locks in new NDCBUs or initiate delivery to NDCBU units installed as replacements.

Upon completing the reviews, keep a copy in your local office and send consolidated copies to the designated growth coordinator for each district. Use PS Form 8143, Equipment Checklist and Follow-up Review, in conducting and recording the reviews. PS Form 8143 is available in this Postal Bulletin (see Exhibit G on page 32), PS Form 8143 is also available on the PolicyNet Web site (http://blue.usps.gov/cpim/.) Click on Forms. Employees conducting the reviews must complete PS Form 1624, Delivery/Collection Equipment Work Request, for any equipment that poses a safety hazard to postal customers or employees. You can order PS Form 1624 from the MDC using Touch Tone order entry (described previously) or download it from the PolicyNet Web site (http://blue.usps.gov/cpim/).
