Send us your existing jack chain sample. We can measure the wire diameter, inside link length and inside link width, then produce the chain in your required length and finish. Material grade and load requirements cannot be determined from appearance alone; we need to check them against the original chain documentation.
You can send us a drawing of the connections in your fixture or enclosure. We can produce the chain to your required wire diameter, inside link length and width, base material, finish and chain length. If you need S-hooks or snap hooks, please include the mounting hole dimensions. We will also confirm whether the total length means the chain alone or includes the end fittings.

If you choose a different material, a modified chain or connecting hardware, we will provide or check the load data for that model. The load values above cannot be applied directly to those products. Jack chain is for light-duty connections and suspension, not lifting or personal fall protection. If you also need the inside link width, other dimensions or specific load data, send us your drawing so we can check them with you.
Material Options
Carbon steel: Zinc plating, other plated finishes or powder coating can meet both protection and appearance needs. Carbon steel suits indoor electrical components, light fixtures and general component sourcing, with a wide choice of sizes and finishes.
Stainless steel: Suitable for electrical enclosure and lighting hardware in outdoor or damp environments where corrosion resistance is needed. We select the grade and finish based on the substances the chain will contact and the specific environment. For exposure to salt or chemicals, the name “stainless steel” alone is not enough to choose the material.
Brass: The base material has a warm yellow metallic appearance, suitable for decorative lighting and visible hardware. You can choose solid brass chain or brass-plated steel chain for the desired look. We will clearly identify the base material we supply.
Copper: Suitable for decorative lighting and custom parts that need a reddish copper color. We can match the surface to your sample so the chain works with the appearance of the other parts. Copper may oxidize and change color in its environment. Let us know if you need to maintain a particular appearance.
Finish Options
Zinc plating: Adds a protective zinc layer to carbon steel. It suits electrical or lighting hardware that needs general protection and a metallic appearance. For continuous outdoor exposure or contact with salt or chemicals, we consider the coating together with the specific conditions of use.
Nickel and chrome plating: Suitable for visible hardware that needs a bright, silver-colored appearance. We can match a sample to coordinate the chain with other hardware. We also identify the base material and plating, so you know what the chain is made of and how its surface is finished.
Brass plating, copper plating and antique finishes: Give steel chain a decorative appearance to match light fixtures, enclosure hardware or decorative parts. These are surface finishes and are supplied separately from solid brass and copper chain.
Powder coating: Suitable for components that need black or other coating colors. We can match the appearance to your color sample. For outdoor use, we use a coating system suited to the relevant conditions.
Polishing: Improves the surface finish and metallic appearance, making it suitable for visible chain and decorative hardware. Polishing does not change the base material. Corrosion resistance still depends on the chosen material and environment.
Send us your required color, finish sample and chain dimensions, and we will explain the finish options available for your base material.
At Tuohai, you can specify the length and packaging for your electrical jack chain. We can print your brand on the packaging and mark the chain model, length and quantity. This makes it easier to distribute the chain under your own brand or select the right specifications during assembly.
Reels: We cut jack chain to the specified length, wind it onto a reel and secure it with stretch film. Reels are convenient for display and sale, and make it easy to feed out and cut the chain during use. Reel specifications and colors can be customized.
Paper boxes/cartons: Cut lengths of chain can be packed directly in paper boxes. Boxes or cartons can also serve as outer packaging for reels. Your company logo, chain model, quantity and other details can be printed on the box for sale and easy identification.
Pails and drums: We offer plastic pails, fiber drums and similar packaging to make the chain easy to take out for sale or production assembly. Packaging size can be selected according to the chain length and quantity packed.
Bags and packs of cut lengths: Burlap sacks, PP bags and resealable bags are available. Burlap sacks or PP bags can be used for bulk supply. Cut chain lengths can be packed in bags by length or piece count, making them easy to take out in set quantities for lighting assembly or use in component packs.
Wooden cases: We use pallet-mounted wooden cases as our standard outer shipping packaging. They make loading and unloading easier during transport and storage, and protect the chain inside. We also wrap the cases with stretch film to secure, seal and protect the outer packaging.
Packaging for the EU market: If your jack chain is sold in the EU, we can customize the packaging to your material and marking requirements. We can also help check the packaging reduction, recycling and labeling requirements under the EU Packaging and Packaging Waste Regulation (PPWR, Regulation (EU) 2025/40). Tell us if you need packaging material information, technical documentation or a declaration of conformity. We will confirm which documents we can provide for the packaging actually selected.
Jack chain can be shipped by sea, air or express courier. Road, rail and combined transport options depend on the destination and available routes. Samples can be sent by a suitable courier or air service. For bulk chain in rolls or packs of cut lengths, we select the shipping method based on weight, volume and delivery requirements.
You can appoint your own freight forwarder. We provide package quantities and cargo information for your chain order, and coordinate pickup and shipment documentation.
We can start with your chain sample and matching parts. We measure the wire diameter, inside link length and inside link width, then check whether the links fit the hooks and connection holes. If you only have photos, including a scale or actual measurements will help us assess the fit.
The same size number alone does not confirm that chains are interchangeable. Even with the same number, the actual wire diameter, link dimensions, material or model-specific load data may differ. We will check the replacement specifications against your original product requirements.
Yes. We can cut and supply the chain to your specified length. Tell us whether you need the length of the chain alone or the total length including end fittings. If you need matched pairs, a set number of pieces per pack or a specific length tolerance, we will confirm what we can supply based on those requirements.
Yes. We supply S-hooks, snap hooks and other connecting hardware, and can preassemble the agreed combinations before shipment. You can choose chain alone or chain with matching hardware. If you need other parts such as end plates or clamps, send us drawings or samples so we can confirm what we can supply.
We can provide dimensional inspection, material and applicable test documentation for jack chain. Dimensional checks include wire diameter, inside link length and width, and chain length. Tell us if you need ISO management system documents, RoHS reports or model-specific test data. We will explain which documents are available for the chain you are buying and what each document covers.
When you change the material or finish, we will recheck the link dimensions, appearance, service environment and model-specific load data with you. Plating or coating may affect the clearance between the links and hooks. If the base material changes, the load rating must also be checked against the new model’s data. Send us the original chain specifications and the changes you need, and we will review them with you.
For repeat orders, you can provide the jack chain model, drawing revision or sample records used previously. We will check the wire diameter, link dimensions, material, finish and supply length. We can also use the previous records for packaging quantities and brand printing. Just let us know what needs to change for this order.
