# Plustool Plustool-55 Matte Black Keyed Door Locks, 5-Pack

Locks: Plustool Plustool-55 is a five-pack of matte black keyed door levers, with the listing claiming matching keys across the set. Its adjustable latch covers two stated backsets, but the package headline calls these door knobs while the feature details describe levers, so verify the selected listing and handle style before ordering.

## At a glance

- Listing claims the five locks use the same keys, which may reduce the number of keys needed across matching doors.
- Adjustable latch is listed for 2-3/8-inch and 2-3/4-inch backsets, with compatibility for doors 1-3/8 to 1-3/4 inches thick.
- The manufacturer claims ANSI Level 3 certification and more than 250,000 opening and closing cycles. These are listing claims, not independently verified results.
- Installation is described as screwdriver-only, with instructions included and reversible left- or right-handed fitting.

## Pros

- Same-key operation is claimed across the set, useful when fitting multiple doors without carrying separate keys.
- The two stated latch backsets and listed door-thickness range offer compatibility options for common installation dimensions.

## Before you buy

- Listing details are inconsistent about product style: the title calls these knobs, while the feature text and specifications describe levers. The five-pack title and included-components entry do not state an exact key quantity, and same-key operation is a manufacturer claim. The latch plate is stated to be unremovable. Confirm the selected listing's exact set and style before buying.

## In the box

- Lock and key (Included): The listing identifies this as an included component but does not state the key quantity.

## A good fit for

- Buyers outfitting several doors who want keyed locks claimed to share one key.
- Installations matching the listed latch backsets and door-thickness range, after confirming measurements.

## Less suited to

- Buyers who specifically need a round knob rather than a lever, unless the selected listing confirms the style.
- Doors requiring a removable latch plate or dimensions outside those listed.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the five-star category, but the sample is small and includes some three- and four-star ratings. No review comments are provided, so the ratings cannot identify specific strengths or concerns. Buyers should weigh them separately from the stated latch dimensions and confirm the handle style and package details.

## Frequently asked questions

### Do all five locks use the same key?
The listing claims the locks are keyed alike, but does not specify the exact number of keys included. Confirm the selected package contents before ordering.
### Will the latch fit my door?
The listed latch adjusts to 2-3/8-inch or 2-3/4-inch backsets and is stated to fit doors 1-3/8 to 1-3/4 inches thick. The latch plate is described as unremovable.
### Are these knobs or levers?
The title calls them knobs, while the feature details identify a lever and give lever dimensions. Check the selected listing to confirm the handle style.
### What is included?
The included-components field lists a lock and key. The product title describes a five-pack, while the exact key quantity is not specified.
