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.

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
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.
