Buying Guide
- Panel compatibility: Confirm the filler plate width (1″, 1/2″, 3/4″) and the panel brand/model (Eaton, Square D QO, Schneider QO, GE, etc.).
- Material and durability: Thermoset plastics offer higher heat and impact resistance; plain plastics may suffice for mild environments.
- Installation method: Peel-and-stick vs. snap-in. Snap-in and tool-free designs save time but may rely on panel surface cleanliness for adhesion.
- Quantity needs: Bulk packs are cost-effective for multi-panel setups; ensure you have the correct widths for your locations.
- Aesthetic and finish: Matte black fillers blend with most interiors; color-matched options may help with visibility or labeling.
- Safety considerations: Fillers prevent accidental contact with live parts and keep dust and debris out of the panel; always follow local electrical codes when replacing or sealing panels.
