What size fireplace grate do I need?

Measure the width and depth of your firebox floor at both the front and the back, since most fireboxes narrow toward the rear. Choose a grate that fits the rear dimension with about an inch of clearance on each side. Sizing to the fireplace opening instead of the floor is the most common mistake and usually results in a grate that won't sit flat.

Do I need a log retainer if I already have a grate?

Not always. Many grates have raised front bars that hold logs in place on their own. A separate retainer is worth adding if you burn shorter logs, stack wood high, or have had logs roll forward as the fire burns down and the stack shifts.

How long does a fireplace grate last?

It depends on the material and how often you burn. A heavy cast iron or thick steel bar grate can last many seasons, while lighter-gauge grates may begin to sag or warp after a few heavy-use winters. Inspect the bars each season and replace the grate once you see sagging, cracking, or bars that have thinned noticeably from heat exposure.

Grates & Retainers

Shop fireplace grates and log retainers for wood-burning fireplaces. A grate lifts logs off the hearth floor for better airflow and a hotter, cleaner burn, while a retainer keeps burning logs from rolling forward toward the opening.

Fireplace Grates & Retainers

A fireplace grate is one of the simplest upgrades you can make to a wood-burning fireplace. By elevating the logs a few inches off the firebox floor, a grate lets air circulate underneath the fire which means faster ignition, more complete combustion, less smoke, and more heat out of the same amount of wood. Log retainers, sometimes called log guards or fire bars, mount at the front of the firebox or attach to the grate itself to keep logs from shifting forward and rolling onto the hearth as they burn down.

Why Buy a Fireplace Grate or Retainer

Better airflow under the fire means easier lighting, a hotter burn, and less smoke.
Keeps logs contained so burning wood stays in the firebox instead of rolling toward the hearth.
Protects the firebox floor from direct contact with coals and embers.
Available in a range of widths and depths, so you can match the grate to your firebox.

What to Consider When Buying

Measure the width and depth of your firebox floor, front and back. Many fireboxes taper toward the rear, so size to the narrower rear dimension.
Leave roughly an inch of clearance on each side for airflow and for the metal to expand as it heats.
Cast iron holds heat well and lasts longer under heavy use; steel bar grates cost less and work well for occasional fires.
Heavier bar stock resists warping over time, which is worth the extra cost if you burn frequently through the season.
If logs tend to roll forward in your fireplace, look for a grate with an integrated retainer or add a separate log guard.
