Expert Verdict — Reviewed by the SuperArbor Pro Desk

Match the J-Block color to the siding field color for a seamless meter trim, or use a contrasting shade for intentional emphasis. Confirm the meter base footprint before ordering between the 16-1/2 in. x 15-1/2 in. and 20 in. x 24 in. sizes. Follow Mastic's fastening and gap guidelines so the accessory moves with panel expansion.

Have electrical meter work coordinated with a licensed electrician and follow local utility clearance requirements before trimming around a meter base.

Order the Mastic Meter Base J-Block in the size and color that matches your siding today.
