Brackets

Corner Brackets

Also known as angle brackets.

Corner-Reinforcing Brackets

Strengthen corners of cases and crates.

Sealing Corner Brackets

A rubber seal protects against moisture around the installation hole.

Flat-Surface Brackets

Crate-Building Brackets

Clamp these brackets to panel edges to quickly assemble crates.

Corner Machine Brackets

Finish-Your-Own Corner Machine Brackets

Machine holes and slots or weld in place.

Side-Hook Lift-Off Panel-Hanging Brackets

Fit brackets together to assemble truck racks, gates, crates, and fences.

Sensor and Switch Mounting Brackets

Position proximity, photoelectric, and light beam sensors and switches.

Structural Framing

T-Slotted Framing Structural Brackets

Connect T‐slotted rails and reinforce joints for structural stability.

Corner Strut Channel Brackets

Wraparound Strut Channel Brackets

Designed to wrap around the sides of strut channel, these brackets provide a stronger hold than other strut channel brackets.

Miniature T-Slotted Framing and Fittings

Build test fixtures, prototypes, and other small structures with this miniature version of T-slotted framing and fittings.

Metal

Multipurpose 304 Stainless Steel

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications.

Corrosion-Resistant 316 Stainless Steel

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Easy-to-Form 6060 Aluminum

Easier to bend and shape than 6061 aluminum, this aluminum is good for framing, cross sections, and structures in construction and marine industries.

Polished Multipurpose 6061 Aluminum 90° Angles

The outside of these 90° angles is polished to either a brushed finish or a mirror-like finish.

Architectural 6063 Aluminum 90° Angles

More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Zinc-Galvanized Low-Carbon Steel 90° Angles

These 90° angles are zinc galvanized for good corrosion resistance.

Low-Carbon Steel 90° Angles

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Anodized Architectural 6063 Aluminum 90° Angles

The anodized coating on these 90° angles forms a bond with the aluminum surface to improve wear and corrosion resistance.

Anodized Multipurpose 6061 Aluminum 90° Angles

An anodized coating forms a bond with the aluminum surface to improve wear and corrosion resistance.

High-Strength 7075 Aluminum 90° Angles

Originally developed for aircraft frames, uses for 7075 aluminum now include a wide range of high-stress parts. It is often used as a replacement for 2024 aluminum because it’s stronger and provides similar performance in all other aspects.

High-Strength 2024 Aluminum 90° Angles

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed. It offers similar performance to 7075 aluminum, but it’s not as strong.

Multipurpose 6061 Aluminum 90° Angles

The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.

Easy-to-Form Marine-Grade
5086 Aluminum 90° Angles

5086 aluminum is used on ships, oil rigs, tanks, and pressure vessels because of its excellent saltwater resistance and formability.

Easy-to-Machine Architectural 385 Brass 90° Angles

Often called architectural bronze, 385 brass is easy to machine and has excellent formability when heated. It is typically used for handrails, ornamental trim, and hardware, such as hinges and lock bodies.

Tool Accuracy Checkers

Clamping and Workholding

Setup Blocks

Use these tight-tolerance blocks as mounting bases and supports to ensure accurate angles and spacing.

Angle Plates with Mounting Holes

Mount workpieces in precisely located holes for repeatable setups.

Fixturing Squares

Build fixtures on multiple sides of these squares.

Angle Plates

Ensure accurate right angles and hold workpieces and fixtures perpendicular to a machine table by securing them to these plates with clamps.

Angle Plates with Mounting Slots

Use these plates to ensure accurate right angles and hold workpieces and fixtures perpendicular to a machine table.

Any-Which-Way Angle Plates

The handle extends the full length and height of these plates for use on any of their six sides.

Robot Tool Mounts for T-Slotted Framing

Connect your robot arm to tools or extensions made from T-slotted framing.
