What are Kee Lite fittings used for?

The most common applications for Kee Lite fittings is hand rail and guard rail, the contours designed into Kee Lite fittings give a smoother appearance and better look than typical non-welded systems. Various other tubular-structures such as retail store fixtures, soft contained play systems, awning, fencing, machinery framework, can be economically produced with Kee Lite Fittings.

What is a Kee Lite structural slip-on tube fitting?

Kee Lite structural slip-on tube fittings are made from a high grade Aluminum Silicon Magnesium Alloy. Kee Lite fittings are used in conjunction with BS EN 755 Aluminum pipe to build structures of unlimited size and scope. Case hardened grub screws attach the fittings securely around the pipe. There is no welding, drilling, or bolting required when building with Kee Lite fittings. The only tools required for building Kee Lite structures are a pipe cutter and a standard hex key.

What style or types are available?

Installation Questions

How do I install Kee Lite fittings?

Installation instructions are available for Download under our "Resources" section, or by contacting us directly and requesting instructions.

What about the fittings being tampered with?

Grub screw inserts are available to deter tampering with a finished Kee Lite structure.

What size hex key is used with Kee Lite fittings?

Kee Lite fittings for 1" pipe sizes (6) use a 1/4" A.F. (across flat) hex key. Kee Lite fittings for 1-1/4" to 2" pipe sizes (7 to 9) use a 5/16" A.F. hex key. The ability to use a 5/16" hex key makes building a Kee Lite structure easy and fast.

Technical Questions

What is the recommended torque for the grub screws?

When constructing with Kee Lite fittings we recommend that you tighten the grub screw to 29 lbs./ft. or 39 Nm. This is approximately "hand-tight." The only exception is size 6 Kee Lite fittings. The setting for tightening the grub screw for this size fitting is 25 Nm ( 19 lb.ft). The theoretical design slip load ( factored ) per grub screw will be around 4.90 KN at this reduced torque setting.

What quality certifications has Kee Lite attained?

The majority of the Kee Lite fittings range are TUV tested and approved.

What type of pipe can be used with Kee Lite fittings?

Kee Lite fittings are designed for use with Schedule 40 or 80 aluminum pipe. View our "Tech Spec" section to the left, or Download a Catalog, for a pipe size chart.

Will Kee Lite fittings corrode if used outdoors?

Kee Lite fittings are Aluminum Silicon Magnesium Alloy (A 356-T6) a highly corrosion resistant alloy. If conditions, require the fittings can be anodized for additional corrosion resistance. Kee Lite grub screws are treated with our Kee Koat® finish to resist corrosion. In Salt Spray test the Kee Koat corrosion resistance was equal to Stainless Steel grub screws in an aluminum fitting. Copies of the salt spray tests available upon request by contacting Kee Industrial Products.

Will the fitting or the grub screw strip tightening to 29 lbs./ft 39Nm?

No, the large diameter grub screws and the British Standard Thread used, along with the alloy of the fitting, give you the correct combination to create a strong mechanical joint between the fitting and the tube.
