Types of Conduit Hangers
EMT Hangers
Electrical Metallic Tubing (EMT) hangers are predominantly used for supporting EMT conduits. Made from robust steel, these hangers are designed to withstand significant weight while maintaining a sleek profile. They are typically installed using screws or bolts, making them a reliable choice for permanent installations.
Rigid Conduit Hangers
Rigid conduit hangers are designed for heavier applications, supporting rigid conduits made from steel or aluminum. Their construction allows them to handle higher loads, making them ideal for industrial settings or locations requiring robustness. Installation usually involves clamps or brackets that provide secure mounting options.
Adjustable Hangers
Adjustable hangers offer flexibility in installation, allowing for height adjustments post-installation. These hangers are suitable for various applications, including commercial and residential projects. Their design varies, with some models featuring a sliding mechanism to accommodate different conduit sizes and configurations.
Plastic Conduit Hangers
Plastic conduit hangers are lightweight and corrosion-resistant, making them perfect for outdoor applications or environments exposed to moisture. Though they have a lower load capacity compared to metal options, they are ideal for less demanding installations where weight is a concern. Installation is often simplified with a snap-on design.
Strap Hangers
Strap hangers are versatile and can support various types of conduits. They are typically made from steel and are installed using screws. Their strength and adaptability make them a common choice for both residential and commercial applications.
Ceiling Hangers
Ceiling hangers are specifically designed for overhead installations, providing robust support for conduit running along ceilings. Their heavy-duty construction allows them to manage significant loads, making them suitable for industrial environments. Installation requires bolting to the structural elements of the ceiling.
Applications of Conduit Hangers
Residential Wiring
In residential settings, conduit hangers are essential for supporting electrical wiring systems. EMT and plastic hangers are common choices, providing the necessary support while ensuring compliance with local building codes.
Commercial Installations
Commercial buildings often require more robust solutions, leading to the use of rigid and adjustable hangers. These systems support complex wiring setups and ensure that electrical conduits remain securely fixed, even in high-traffic areas.
Industrial Facilities
In industrial environments, conduit hangers must endure heavy loads and adverse conditions. Rigid conduit hangers and ceiling hangers are frequently employed due to their durability and load-bearing capabilities.
Outdoor and Exposed Installations
For outdoor applications, plastic conduit hangers are preferred due to their resistance to corrosion. They provide a lightweight solution for installations that may be exposed to the elements, ensuring longevity and reliability.
Best Practices for Installation
Planning the Layout
Before installation, it’s crucial to plan the layout of your conduit system. Consider factors such as load requirements, spacing between hangers, and accessibility for future maintenance.
Using the Right Tools
Employ the appropriate tools for installation, including drills, screwdrivers, and wrenches. Ensuring that you have the right tools at hand will streamline the process and enhance safety.
Following Load Specifications
Always adhere to the manufacturer’s load specifications when selecting and installing conduit hangers. Overloading can lead to failures, risking both safety and system integrity.
Regular Inspections
Conduct regular inspections of installed hangers to check for signs of wear, corrosion, or loosening. Early detection of potential issues can prevent costly repairs and ensure reliable operation.
