PCLM-GMP – Textron Aviation OEM Cable Clamp
Available now on the Airparts.aero Marketplace.
Overview
The PCLM-GMP is a genuine OEM, one-piece, hinged plastic loop clamp, an advanced fastening solution for securing wiring, tubing, and fluid lines within modern aircraft. Specified by Textron Aviation and manufactured by industry leaders like UMPCO, this clamp is engineered from a high-performance, fire-retardant nylon material. Its innovative hinged design allows for easy one-handed installation, while its lightweight and non-conductive properties make it a superior choice over traditional metal clamps in many applications, especially within composite airframes.
Key Features
- High-Performance Nylon Construction: Molded from a durable, high-temperature, fire-retardant black nylon. This material is lightweight, strong, and resistant to most aviation fluids and chemicals.
- Hinged, One-Piece Design: Features an integral hinge that allows the clamp to be opened wide for easy placement over a wire bundle or tube and then closed securely with a single fastener, significantly speeding up installation and maintenance.
- Non-Conductive & Non-Abrasive: The all-plastic construction is electrically insulating, preventing any risk of chafing through wire insulation and causing a short circuit. The smooth, molded surface will not abrade wire bundles or tubing.
- Vibration Damping: The inherent flexibility of the nylon material provides a degree of vibration damping, protecting the secured components from the damaging effects of high-frequency airframe vibration.
- Lightweight: Offers a significant weight savings compared to traditional metal and cushioned "Adel" style clamps, contributing to the overall efficiency of the aircraft.
Technical Specifications

- Component Type: Hinged Plastic Loop Clamp
- Material: High-Temperature, Fire-Retardant Nylon
- Color: Black
- Mounting: Secures with a single #10 size screw or bolt.
- Bundle Diameter: (The "GMP" suffix corresponds to a specific nominal bundle diameter for which the clamp is designed).
- Temperature Range: Suitable for a wide range of operating temperatures found within the airframe.
Aircraft Compatibility
The PCLM-GMP is a standard component used across a wide range of modern aircraft, including many specified by Textron Aviation (Cessna, Beechcraft) for their latest-generation platforms.
- Common Applications:
- Wire Harness Routing: The primary application is to secure and route electrical wiring harnesses throughout the fuselage, wings, and empennage.
- Fluid Line & Tubing Support: Used to fasten lightweight pneumatic lines, drain tubes, and other fluid-carrying conduits.
- Composite Airframe Installation: Its non-conductive nature makes it ideal for direct installation onto composite structures without the need for additional insulation to prevent galvanic corrosion.
Applicable Textron Aircraft
- Skyhawk
List not comprehensive, may be applicable on other models.
Applications
The PCLM-GMP is the modern solution for securing and routing internal components:
- Wire Management: Provides neat, secure, and lightweight routing for complex wiring systems, preventing chafing and interference.
- Weight Reduction Programs: A preferred choice when reducing weight is a primary goal, replacing heavier, multi-piece metal clamps.
- Avionics Upgrades & Installations: An easy-to-use and reliable clamp for securing the wiring associated with new avionics installations.
Why Choose PCLM-GMP?
Protecting an aircraft's wiring is critical for the safety and reliability of its complex electrical and avionics systems. The PCLM-GMP offers a superior solution to older metal clamps by eliminating the risk of abrasion and short-circuiting while saving weight. Its one-piece hinged design simplifies installation, reducing maintenance time and costs. Using a genuine OEM-specified part ensures the clamp is made from the correct fire-retardant material and has the strength required for a safe and airworthy installation.

The PCLM-GMP represents an evolution from the traditional MS21919 "Adel" clamp. While the metal, cushioned Adel clamp is still a mainstay for high-temperature or heavy-duty structural applications, the PCLM-GMP hinged plastic clamp offers distinct advantages in general-purpose routing. The one-piece design eliminates the need to handle a separate cushion and fastener, preventing dropped hardware in inaccessible areas. The "positive lock" design of the hinge and fastening hole ensures that even if the screw loosens slightly, the clamp cannot spring fully open, providing an extra layer of security for the bundle it contains. This combination of safety, simplicity, and weight savings is why it has become a standard in modern airframe design.
Note: Installation must be performed in accordance with the aircraft manufacturer's standard practices manual. Ensure the clamp is the correct size for the bundle it is securing—the bundle should be held snugly without being pinched or crushed. Use the specified #10 fastener and torque to the correct value.
