Not sure why you couldn't claim check your backpacks as described on the Rockies website. Softside bags are a permitted item but probably too large, so would be in the restricted category. Still, they have the claim check tent for those items. Food seems to be a permitted item, except that any fruit or veggie larger than a grapefruit must be sliced.
Standing 72'' tall and just 12'' wide, this single-tier locker brings space-conscious storage to bedrooms, break rooms, and beyond. This design is awash in a crisp white finish and sports brushed nickel hardware – including a convenient double hook for coats and bags. On the front, you’ll find a chrome-plated nameplate and latch (locks not included). This product comes backed by a five-year manufacturer warranty. To clean, simply wipe down with a damp cloth.
Locking options: various types of key locking or padlocking facility are available now. Key locking options include flush locks, cam locks, or locks incorporated into a rotating handle; padlocking facilities may be a simple hasp and staple, or else a padlocking hole may be included in a handle, often called a latchlock. More modern designs include keyless operation, either by coin deposit (which may or may not be returned when use of the locker terminates), or by using electronic keypads to enter passwords for later reopening the locker. Some older lockers used a drop-latch which was incorporated into the door handle, and slid up and down and could be padlocked at the bottom in the "down" position, but these are less used now. Three-point locking is not possible with this type of latch, because it needs to be operated by means of a latch that rotates rather than slides up and down; so this drop-latch is probably a less secure locking option, which may be why it is little used nowadays. Prefect Combination locks are very popular in school lockers used in the UK due to their ease of use and the time and cost saved in the removal of locker keys.
