Base Plate Cover

What This Base Plate Cover Does

This base plate cover is installed at ground level around surface mount post base plates for Jayco Letter Locker mailboxes. When posts are secured to concrete pads, mounting hardware remains visible at ground level.

This cover conceals exposed mounting bolts and metal edges, creating a clean, finished appearance while protecting the hardware.

Key Benefits of This Base Plate Cover

Here is a quick breakdown of the practical advantages this cover provides once installed:

• Creates a clean, finished look by covering exposed base plate mounting bolts and hardware
• Protects edges from wear

• Works for new installations and replacements
• Backed by a Conditional Lifetime Warranty

This base plate cover is available in multiple configurations so it can match your mailbox setup and surrounding environment.

Textured Color Options

This base plate cover is available in 5 powder-coated textured finishes:

What It Fits (Models and Sizes)

Universal Compatibility:

This base plate cover fits all Jayco Letter Locker models installed with surface mount posts. Available in two versions to match your post type:

Important: This cover is for surface mount installations only. Not compatible with in-ground posts (which do not use base plates).

How to Measure Before You Buy

To confirm compatibility before ordering, follow the steps below.

Step 1: Identify Your Post Shape 

Measure your post cross-section: square posts are 4" x 4", round posts are 4" diameter.

Step 2: Verify Base Plate Presence 

Check at ground level for a flat metal base plate where the post connects to the concrete. Mounting bolts should be visible around the perimeter.

Step 3: Select Correct Version

• 4" x 4" square post = Square base plate cover

• 4" diameter round post = Round base plate cover

Diagram suggestion: Show a top-down view that compares a square post and a round post. The square post should be labeled 4" × 4" with a square base plate. The round post should be labeled 4" in diameter with a round base plate. Include measurement arrows.

Installation Guide

Installation is straightforward and can typically be completed with basic tools.

Steps:

1. Install the surface-mount post and secure the base plate to the concrete, following the manufacturer’s instructions.
