Frequently Asked Questions

Does the fitting come with set screws?

Yes, Kee Klamp, Kee Lite and Kee Access fitting comes with the required set screws. If you would like extra set screws they are available for purchase. Stainless set screws are also available for additional corrosion protection.

Are these fitting available in colors?

Yes. Kee Klamp, Kee Lite, Kee Access fittings and pipe can be powdercoated to give them a durable baked on paint finish. Powdercoating is extremely durable and will give your railing or structure a really sharp look.

Please contact us if you have any questions about powdercoating.

What kind of pipe can be used with Kee Klamp and Kee Lite fittings?

Kee Klamp and Kee Lite components are designed to be used with Schedule 40 Pipe (or Schedule 80), but can also be used with other types of pipe or tube.

When aquiring your own pipe and tube it is important to know the actual OUTER DIAMETER of your pipe/tube . Do not assume that just because it says 1 Inch Pipe/Tube for instance, that the outer diameter is actually 1 inch. This mistake frequently results in returns.

If you are purchasing fittings and pipe from our website, match the pipe size with the fitting size such as Size 7 pipe with Size 7 fittings, Size 8 pipe with Size 8 fittings, etc. You may also refer to our SIZING CHART for further help.

How can I be sure I'm ordering the right size fittings?

If you already have pipe, please measure the outer diameter of your pipe and compare it to the chart on this page. For simplicity we have a printable pipe chart that you can use to measure your pipe. Be sure to follow the instructions on the sheet to guarantee an accurate measurement.

If you are purchasing your pipe from us, then be sure to match the size after the dash "-" on the fittings to the size of the pipe. For instance, a 10-7 is a size 7 fitting. Select size 7 pipe to go with that fitting.
