If you are looking for a fireplace “lintel clamp” to keep a chimney damper from closing, the products below are damper clamps, also called flue stops. They are designed to hold a damper open for ventilation when vented gas logs are installed. The Midwest Hearth clamp is best for buyers who want two bolt lengths and an FHA inspection-focused option; the stainless-steel LRWZOV and GAQUECY two-packs suit buyers looking for a pair of clamps. Check the product description and your fireplace setup before choosing: these are not replacement fireplace-door clips.

Midwest Hearth Fireplace Damper Clamp

Best for: Homeowners installing gas logs who want a damper clamp with inspection-focused positioning. This product is listed as FHA approved and is described as suitable for gas log installations where an inspection requirement applies.
The clamp locks a fireplace damper in the open position while gas logs are in use. Its listed safety purpose is to help prevent the damper from closing and obstructing ventilation. The package includes two bolt lengths, which the manufacturer says allow a secure fit on standard damper blades without extra hardware or tools.
Why it stands out: Among these options, it provides the clearest detail about included hardware and inspection use. Choose it if having two bolt lengths and an FHA inspection-focused product description matters to your purchase.
Limitation: The stated fit is for standard damper blades, not every fireplace configuration. Confirm that your damper shape and installation requirements match before relying on it.
VKQ Fireplace Damper Clamp

Best for: Buyers who need one clamp for a vented gas log installation and prefer a product described as heavy-duty metal. VKQ says the clamp keeps the damper partially open to help maintain ventilation and prevent gas buildup.
The listed design is compatible with most standard fireplace dampers. Its metal construction is described as suitable for high temperatures and long-term use. The product is presented as a flue stop for gas logs rather than a fireplace-door attachment.
Why it stands out: It offers a straightforward single-piece option with a stated gas-log safety purpose. Choose this if you want one clamp and your damper falls within the “most standard” configurations described by the seller.
Limitation: The listing does not specify multiple bolt lengths or provide detailed damper measurements. Check fit and installation needs rather than assuming “universal” compatibility means it will fit every fireplace.
Raneped Two-Piece Damper Clamp Set

Best for: Buyers who want two steel clamps and a simple installation approach. Raneped describes this set as usable with a fireplace or wood stove, and says the clamps attach to the damper to control whether it stays open or closed.
The listed features include a durable steel construction and a clamp-on installation. Having two pieces may suit a buyer who needs more than one clamp, but the product details do not specify which fireplace layouts require one or two clamps.
Why it stands out: This is a basic two-piece choice for shoppers comparing quantity and material. Choose it if steel construction and a simple clamp attachment are your main priorities.
Limitation: The description does not provide dimensions, bolt-length options, or a specific claim of gas-log inspection approval. Verify that it meets the requirements for your appliance and local installation before use.
LRWZOV Stainless Steel Damper Clamp

Best for: Buyers looking for two stainless-steel clamps for a vented gas log setup. The listing says the clamps hold the damper in a fixed-open position so combustion gases can vent through the chimney.
The product is described as fitting most standard fireplace dampers without complex measurements or modifications. Its stainless-steel construction is presented as resistant to rust and corrosion and intended to withstand fireplace heat. The package is listed as a two-piece set.
Why it stands out: Compared with the single-clamp options, it offers two pieces and emphasizes stainless steel. Choose it if those features fit your needs and the damper dimensions match the product’s intended standard fit.
Limitation: The listing does not state exact dimensions or provide a detailed fit chart. “Most standard” should not be treated as a guarantee for unusual or oversized dampers.
GAQUECY Stainless Steel Flue Stop

Best for: Buyers who want a two-pack of stainless-steel damper stop clamps with screw fastening. The product is designed to mount on chimney damper blades and prevent accidental closure.
GAQUECY says its clamps keep vents open to a minimum for a gas-log fireplace. The listed installation method is to tighten the screws. The stainless-steel construction and two-piece quantity make this option relevant to shoppers comparing basic hardware sets.
Why it stands out: It combines a stated anti-closure purpose with a two-pack and screw-tightened installation. Choose it if those details match your damper and you are looking for a straightforward flue stop.
Limitation: The product information does not give exact dimensions or describe the adjustment range. Confirm the fit and required opening with the fireplace or gas-log instructions before installation.
Buying Guide: How to Choose a Fireplace Damper Clamp
Are you looking for a lintel clamp or a damper clamp?
These terms can refer to different fireplace parts. A lintel is a structural member above a fireplace opening, while the products in this list attach to a chimney damper blade. If your goal is to prevent a damper from closing, search for a damper clamp, damper stop, or flue stop. If you need a part that holds a fireplace door or screen, these products may not be suitable.
Is the clamp for vented gas logs?
Several products here are specifically described for gas logs. A damper clamp can hold the damper open to preserve a path for exhaust gases, but installation requirements vary by appliance and location. Follow the gas-log manufacturer’s instructions and applicable local requirements. Do not assume a clamp makes an otherwise unsuitable fireplace safe for gas logs.
How should you compare the materials?
The product descriptions identify steel or stainless steel construction on several options. Material alone does not confirm that a clamp fits your damper or meets your appliance’s instructions. Compare the exact product details, including any supplied screws or bolts, and select hardware intended for the heat and application described by its manufacturer.
Does a two-pack mean you need to install both clamps?
Not necessarily. A two-pack describes the quantity supplied, not the number required for every fireplace. The right number and placement depend on the damper and installation instructions. Do not add or position clamps based only on the package quantity; use the directions for the clamp and gas-log set.
What fit details should you check?
Look for damper-blade compatibility, clamp dimensions, fastener type, and any included bolt-length choices. The Midwest Hearth listing specifically mentions two bolt lengths, while several other listings provide broad “standard” or “most fireplaces” fit descriptions. If the listing lacks measurements, compare your damper with the seller’s fit information before ordering.
When does inspection approval matter?
The Midwest Hearth product is listed as FHA approved and positioned for inspection-related use. That statement should not be interpreted as approval for every fireplace, jurisdiction, or gas-log installation. Check with the relevant inspector or installer if you are selecting a clamp for a home sale, new installation, or required inspection.
Frequently Asked Questions
What does a fireplace damper clamp do?
A damper clamp attaches to the damper blade to help keep it from closing beyond a set position. For vented gas logs, the products listed here are intended to help preserve an exhaust path.
Can I use a damper clamp as a fireplace-door clip?
No product in this comparison is described as a fireplace-door clip. These are damper or flue-stop clamps. Match the replacement part to the function and model requirements of your fireplace door.
Are these clamps compatible with every fireplace?
No. Some listings describe compatibility with most standard dampers, but the products do not provide universal fit measurements. Check your damper shape and dimensions against the product details.
Can a damper clamp replace professional installation advice?
No. Use the appliance and clamp instructions, and consult a qualified installer or inspector when requirements are unclear. A clamp does not replace proper installation or ventilation planning.
Which option includes two bolt lengths?
The Midwest Hearth Fireplace Damper Clamp is listed with two bolt lengths. The other products should be checked individually for included fasteners and fit details.
