All-O-Matic #40 Dacromet Rust-Free Roller Chain – 100 ft Reel | Heavy-Duty Sliding Gate Operator Drive Chain

The All-O-Matic #40 Dacromet Rust-Free Roller Chain – 100 ft Reel is a heavy-duty, corrosion-resistant drive chain designed for reliable mechanical power transmission in residential, commercial, and compatible industrial sliding gate operator applications. Featuring a specialized Dacromet protective coating, this #40 roller chain delivers enhanced resistance to rust, oxidation, and environmental deterioration, making it an excellent solution for demanding outdoor gate automation installations.

Unlike conventional untreated steel roller chains, Dacromet-coated chain utilizes a zinc-aluminum flake protective coating engineered to help shield metal surfaces against corrosion caused by rain, humidity, moisture, and other environmental conditions. This protective finish makes the chain particularly suitable for exposed sliding gate installations, commercial access control systems, outdoor industrial facilities, and properties where long-term corrosion protection is essential.

Supplied in a 100-foot continuous reel, the All-O-Matic #40 Dacromet Roller Chain provides professional gate installers, access control contractors, and maintenance technicians with a convenient bulk solution for new gate installations, drive chain replacements, and ongoing service requirements. The continuous reel allows installers to measure and cut the chain to the appropriate length for individual gate configurations, accommodating different gate openings, travel distances, and chain-drive arrangements.

Designed for use with compatible All-O-Matic sliding gate operators and other automated gate systems requiring ANSI #40 roller chain, this product supports consistent mechanical power transfer between the operator's drive sprocket and gate assembly. Its roller chain construction promotes reliable engagement with properly matched sprockets, helping maintain smooth gate travel and efficient drive system operation.

Whether completing a new residential or commercial sliding gate installation, replacing corroded chain on an existing operator, or maintaining multiple automated access points, the All-O-Matic #40 Dacromet Rust-Free Roller Chain provides a professional-grade solution for applications requiring durable, corrosion-resistant #40 roller chain.

Compatibility & Installation Information

The All-O-Matic #40 Dacromet Rust-Free Roller Chain – 100 ft Reel is intended for sliding gate operators and chain-drive assemblies specifically designed to accommodate ANSI #40 roller chain.

It may be suitable for compatible All-O-Matic sliding gate operators and other manufacturers' automated gate systems when chain dimensions, sprocket configuration, and mechanical load requirements match the installation.

Before installation, verify the following:

• Correct Chain Size: Confirm that the gate operator requires ANSI #40 roller chain rather than #41, #50, or another chain configuration.

• Sprocket Compatibility: Ensure the operator's drive sprocket and idler assemblies are designed for #40 roller chain.

• Required Chain Length: Measure the gate travel distance and chain routing to determine the correct installation length.

• Proper Chain Tension: Adjust chain tension according to the gate operator manufacturer's installation requirements.

• Chain Alignment: Maintain correct alignment between the drive sprocket, idler components, and gate chain attachment points.

• Connecting Hardware: Verify whether master links, connecting links, chain brackets, and other installation components must be purchased separately.

• Working Load Requirements: Confirm the chain's mechanical load rating is suitable for the intended gate operator.

• Routine Maintenance: Inspect, clean, and lubricate the chain as recommended by the manufacturer.

Important: ANSI #40 and #41 roller chains share a nominal 1/2-inch pitch but differ in roller dimensions, inner width, and load characteristics. They should not be considered interchangeable without verifying the operator manufacturer's requirements.

Not all All-O-Matic sliding gate operators use #40 roller chain. Always confirm the correct chain size and specifications for your particular operator model before ordering.

Connecting links, offset links, chain brackets, and other installation hardware should be purchased separately unless specifically listed as included.

What Is Dacromet Rust-Free Chain?

Dacromet is a corrosion-resistant coating technology that utilizes zinc and aluminum flakes within a protective inorganic coating system. The coating creates a barrier against environmental exposure while providing additional corrosion protection through its zinc-containing formulation.

Unlike stainless steel chain, which relies on the corrosion-resistant properties of its base metal, Dacromet-coated roller chain uses a specialized protective surface treatment applied to steel components.

This makes Dacromet-coated chain an attractive alternative for installations requiring enhanced corrosion resistance without necessarily using stainless steel construction.

Advantages of Dacromet-Coated Roller Chain

• Enhanced Rust Protection: Helps resist corrosion caused by rain, humidity, and moisture exposure.

• Protective Zinc-Aluminum Coating: Provides an additional corrosion-resistant surface treatment.

• Outdoor Application Suitability: Beneficial for exposed sliding gate installations.

• Reliable Mechanical Performance: Supports consistent chain-drive operation when properly specified and maintained.

• Reduced Corrosion-Related Deterioration: Helps minimize rust-related damage compared to untreated steel chain.

• Professional Installation Flexibility: Suitable for new installations and replacement projects requiring compatible #40 roller chain.

• Long-Term Service Potential: Can help extend usable service life in suitable operating environments.

Although marketed as rust-free, Dacromet-coated chain is not completely immune to corrosion. Coating damage, abrasion, environmental exposure, and inadequate maintenance can affect corrosion resistance over time.

Dacromet vs. Stainless Steel vs. Standard Black Chain

Selecting the appropriate roller chain finish is important for maintaining dependable sliding gate operation under different environmental conditions.

Dacromet-Coated Chain: Provides corrosion protection through a specialized surface coating, making it an excellent option for outdoor sliding gate installations where conventional steel chain may deteriorate more quickly.

Stainless Steel Chain: Offers corrosion resistance throughout its base material rather than relying solely on a surface coating. However, stainless steel is not necessarily stronger or more wear-resistant than coated carbon steel.

Standard Black Chain: Provides a conventional roller chain solution for installations where enhanced corrosion protection is not a primary requirement.

The appropriate chain should be selected based on the gate operator's specifications, environmental exposure, chain working-load rating, and maintenance requirements.

100-Foot Reel Advantages

The All-O-Matic #40 Dacromet Rust-Free Roller Chain is supplied in a 100-foot reel, making it a practical solution for professional installers and maintenance departments requiring larger quantities of chain.

Benefits of Bulk Chain Packaging

• Multiple Installations: Provides chain material for several compatible sliding gate projects.

• Custom Chain Lengths: Allows installers to measure and cut chain to individual gate requirements.
