Product Description

The C50 is a combination fitting which couples the F50 socket and the M50 slip-on fitting.  There is 170 degrees of variation in the angle that can be created with a combination fitting.

There are two different versions of the C50:

  • The C50 is joined together with a rivet.  This allows the two fittings to swivel freely.
  • The C50B is joined together with a bolt kit.  This allows the two fittings to be tightened together into a fixed angle. 

Note: The primary purpose of the C50B is to reduce the movement between the F50 and M50 fittings in a railing application. The C50B needs to be used between at least two fixed posts/uprights or fixed connections, and should not be used to cantilever. 

Common Usage

The C50 is typically used to create angular supports and braces within a structure. 

The C50B is used whenever a tighter swivel connection is desired. We recommend using the C50B for swivel socket handrail applications such as our Surface C50 handrail kit.

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. powder-coating is extremely durable and will give your railing or structure a really sharp look.

Please contact us if you would like to discuss powder-coating with a projects specialist.

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 acquiring 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.
