Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Upgrade your mailbox security with the Prime-Line Nickel Steel Clockwise Mailbox Lock. Built from durable steel with a sleek nickel finish, this clip-on lock is designed for reliable everyday use and easy, tool-free installation on Florence-compatible mailboxes. A precise 5-pin tumbler, clockwise rotation, and two included keys combine to give you straightforward control and peace of mind.

Key features that set this lock apart

  • Nickel-plated steel construction delivers a robust, corrosion-resistant housing that stands up to regular handling and weather exposure.
  • 5-pin tumbler provides dependable engagement and smoother operation than thinner, simplified cores.
  • Clockwise rotation cylinder for natural, intuitive use when opening your mailbox.
  • Clip-on design enables quick, no-drill mounting on compatible mailboxes, simplifying replacement and maintenance.
  • Includes 2 keys so you have a spare on hand for family members or property management needs.
  • Compact dimensions—4.9" tall, 3.8" wide, and 1.25" deep—made to fit standard Florence-style mailbox doors without crowding the opening.

Who should consider this Prime-Line mailbox lock?

  • Homeowners replacing a worn or jammed mailbox lock to restore secure access to mail and small parcels.
  • Property managers and landlords overseeing rental units that use Florence-style or compatible mailboxes.
  • Anyone seeking a straightforward, durable replacement lock with a clean, contemporary finish to match existing hardware.

How this lock solves real-world needs

  • Keep mail secure with a sturdy 5-pin core designed for reliable operation under frequent use.
  • Choose convenience with a clip-on installation that minimizes downtime and tools required.
  • Maintain accessibility for authorized users with two included keys, preventing lockouts during busy mornings.
  • Harmonize with your mailbox’s look thanks to a polished nickel finish that complements other hardware.

Practical use and care

Place this lock on Florence-compatible mailbox doors where a dependable, low-maintenance solution is most needed. To extend longevity, wipe with a soft, dry cloth and avoid harsh chemicals; occasional light lubrication of moving parts can help maintain smooth operation over time.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
