Raises mail above moisture
The liner creates a raised surface so letters and small parcels are less likely to sit directly on wet metal, rust, or pooled condensation.
Wet mail solution
Mail getting wet in your letterbox?
Many outdoor letterboxes collect water, condensation, or damp patches on the bottom. DryBox Liner is a custom 3D printed insert that raises mail above the wet floor and lets air move underneath.
Made for your mailbox size
Generic mats often move around or do not fit older boxes. We use your internal measurements to make a custom letterbox insert.
Useful before replacing the box
If the letterbox only has mild moisture or a rusty base, a liner can be a low-cost improvement before replacing the whole mailbox.
Important
It helps with damp contact. It does not repair leaks.
If rain is pouring through the door, roof, or lock, the letterbox should still be repaired. The liner is designed to reduce contact between mail and the damp base, especially where moisture sits after rain or humidity.
