Chemical-Resistant PVC Tubes

Because PVC resists many acids and alkalies, it’s widely used for tanks and in chemical-processing applications. Also known as PVC Type 1.

Clear Scratch- and UV-Resistant Acrylic Tubes

This extruded acrylic offers similar performance as cast acrylic at a lower cost.

Clear Impact-Resistant Polycarbonate Tubes

At only half the weight of glass, polycarbonate maintains excellent impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.

Multipurpose Flame-Retardant
Garolite G-10/FR4 Rectangular Tubes

These rectangular tubes are flame retardant, machinable, and electrically insulating.

Easy-to-Machine Garolite LE Rectangular Tubes

Easily turn these rectangular tubes into parts for transformers and switchgears using high-speed tooling.

Structural FRP Fiberglass Square Tubes

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Arc-Resistant GPO3 Fiberglass Square Tubes

Route and insulate wire using these square fiberglass tubes, which fit better along edges and around corners than round tubes.

Ultra-Strength Lightweight
Carbon Fiber Square Tubes

Mount these lightweight tubes to flat surfaces in place of aluminum to create structural frames, machinery components, and robotics.

Structural Framing

Strut Channel

Press-Fit Framing and Fittings

No need for fasteners—friction holds this framing together. Use press-fit framing and fittings to assemble carts, enclosures, and partitions.

Heavy Duty Locking-Slotted Framing and Fittings

Build structures that stand up to more vibration and movement than T-slotted framing but with the same versatility and installation ease. Instead of T-shaped slots, these rails have slots that turn up and inward to keep connections rigidly aligned together.

Shipping Tubes

Square Adjustable-Length Shipping Tubes

These tubes are easier to label and stack than round tubes. To adjust the length, push the ends of the tube together or pull them apart.

Rectangular Adjustable-Length Shipping Tubes

Less likely to tip over or roll around during shipping compared to round and square tubes, these tubes are wider and flatter. Push the ends together or pull them apart to adjust the length.

Recycled Plastic Square
Adjustable-Length Shipping Tubes

Made of recycled polyethylene, these shipping tubes are a sustainable alternative to other plastic shipping tubes. They won’t roll around, making them easier to label and stack than round tubes.

Square Cut-to-Length Shipping Tubes

Because of their square shape, these tubes can be stacked, and the flat surface is easier to label than a round surface.

Square Shipping Tubes with Internal Holder

Secure drill bits and other long, sharp items firmly in place for storage or transit. The end caps on these shipping tubes have an internal holder that keeps your item centered between the walls of the tube.
