When it comes to building frameworks, routing cables, or securing structures to a floor or wall, the base fitting you choose makes all the difference. While metal fittings have traditionally dominated the market, they aren't always the best fit for modern applications—especially where weight, corrosion, or electrical conductivity is a concern.
Enter the Plastic Mounting Plate & Tube Base Plate. Lightweight, incredibly durable, and highly versatile, this simple pipe flange is becoming the go-to component for DIYers, shopfitters, and electrical engineers alike.
But what sets our plastic floor flanges apart from the rest? The ability to custom-fit them to absolutely any profile.

We Can Make These Fit ANY Sized Tube, Pipe, or Square Tube
One of the biggest frustrations in construction, plumbing, and electrical work is trying to source a base plate that perfectly matches an obscure pipe diameter or a non-standard square profile. Off-the-shelf sizes often leave you with a loose, rattling fit or require messy adaptations.
At Joints and Connectors, we’ve solved this problem. We can manufacture our plastic mounting plates to fit any sized tube, pipe, or square tube.
- Round Pipe Floor Flanges: Whether you are working with standard metric PVC, imperial sizes, or bespoke extruded tubing, we can adapt the inner collar to grip your pipe perfectly.
- Square Tube Mounting Plates: Need to mount square tubing to a floor or wall? Our square tube base plates offer a flush, secure fit without the need for welding or heavy metal brackets.
- Custom Dimensions: From micro-tubing used in intricate displays to heavy-duty structural PVC, just let us know your dimensions, and we will provide the perfect secure fit.
Applications in the Electrical Space
Our plastic mounting plates are seeing a massive surge in popularity within the electrical sector. Unlike metal, plastic is naturally non-conductive, making it a far safer and more practical choice for electrical installations.
Here are the top long-tail uses for our flanges in the electrical space:
- Electrical Conduit Mounting Plates: When routing electrical wires, a secure PVC conduit floor flange ensures that vertical and horizontal conduit runs are safely anchored to floors, walls, or ceilings without risking electrical shorts.
- Non-Conductive Base Plates for Antennas: Radio and Wi-Fi antennas require mounting bases that won't cause signal interference. A heavy-duty plastic pipe base provides the perfect structural support with zero signal disruption.
- Cable Containment and Routing: For securing containment pipes or cable management tubes across factory floors or commercial buildings.
- Sensor & Lighting Brackets: Ideal for acting as a non-metallic tube base for CCTV poles, motion sensors, or outdoor lighting, particularly in areas exposed to weather where a metal flange would rust.
- Junction Box & Enclosure Support: Easily mount custom electrical enclosures to pipe frameworks using our flanges as secure anchor points.
Applications
Because our plastic tube bases are completely rust-proof, lightweight, and customisable, they capture a massive variety of use cases across multiple industries. Here are just a few of the ways our customers are using them:
1. DIY Furniture & Structural Frameworks
If you are searching for "how to mount square tubing to a floor" or need a "lightweight tube base plate for DIY furniture," these flanges are the answer. They are perfect for building custom shelving, retail clothing racks, or garage storage frameworks.
2. Hydroponics & Wet Environments
Metal rusts; our plastic floor flanges do not. If you are building agricultural setups, aquariums, or hydroponic racks, a "rust-proof plastic pipe base" is essential. They act as the perfect anchor points for PVC water delivery systems or structural plant supports.
3. Marine and Outdoor Applications
Saltwater and rain make short work of standard iron flanges. A "corrosion-resistant plastic pipe flange" is ideal for boat handrails, outdoor decking barriers, or securing outdoor plumbing pipes safely to exterior brickwork.
