Kee Klamp® pipe fittings and components join steel pipes together, simply and effectively, using slip-on components to create versatile and rigid tubular structures. Kee Klamp® has been developed and refined for more than 75 years, resulting in an extensive range of pipe fittings and components suited for any need.
Fittings For Function
These modular pipe fittings can be used as components in our collective fall protection systems, including safety railing and handrails. They are suited for railing on level surfaces, ramps, and stairs, and are available in galvanized steel, aluminum, or powder coated for internal or external uses.
Fit for tough environments in need of safety barriers or simple safety solutions, Kee Klamp® is designed to provide durability into structures. Kee Klamp® pipe fittings are the most cost-effective safety solution for barrier requirements to protect people, equipment or on-site inventory.
There is no welding or threading required, making installation costs and time, effective.
Kee Safety is the original manufacturer of Kee Klamp®
The simple but effective engineering principle of Kee Klamp® fittings is the foundation of the most versatile pipe connection system available. There are many variations of pipe fitting to suit a wide range of applications, thus providing the versatility to achieve virtually any structural configuration.
Lightweight and Versatile Components
Kee Klamp® pipe fittings are made from cast iron* manufactured to the requirements of ASTM A47-77-32510, and EN 1562 & EN153. It is also galvanized to the requirements of EN ISO 1461. A range of fittings to suit eight sizes of pipe is available.
No Welding or Threading
Hex set screws firmly lock the pipe into the fitting, a simple hexagon key is the only tool required to firmly lock the pipe into the fitting. Set screws are manufactured in case hardened steel and are protected against corrosion by Kee Koat®. This combined with the ThreadKoat® (patented) factory applied coating for the threaded recesses ensures that Kee Klamp fittings achieve longer life and better corrosion resistance.
A Kee Klamp® fitting (size 5 to 9) can support an axial load of *2000 lbs (900 kg). per grub screw with the grub screw tightened to a torque of 29 lbs. ft.(39 Nm).
* Materials used can vary according to application. Please refer to manufacturer for detailed specification.
Kee Klamp pipe fittings are typically used to build various tubular structures such as railing, racking, retail store fixtures, soft contained play systems, awning, fencing, machinery framework, plus 1001 other applications. Kee Klamp fittings are used in conjunction with steel pipe to build structures of unlimited size and scope. Casehardened grub screws attach the fittings securely around the pipe. There is no welding or drilling required when building with Kee Klamp fittings.
What is a Kee Klamp structural pipe fitting?
Kee Klamp slip-on pipe fittings are cast-iron pipe fittings, which conform to BS EN 1562/1563, SAE J158 A grade M3210, ASTM A47-77-32510.

Besides the long lasting galvanised finish, Kee Klamp pipe fittings can be powder coated to any RAL color.
Can different sizes of tube be used when building tubular structures with Kee Klamp pipe fittings?
Yes, Kee Safety has designed several of its fittings with multiple sized barrels to allow for the utilization of different sizes of pipe when building tubular structures. View our Technical Details section, or download a catalog, for a pipe size chart.
What are the structural design specifications when building with Kee Klamp pipe fittings?
An independent laboratory has tested Kee Klamp pipe fittings on terms of load capacity and vibration resistance. Using these results, we have developed a series of structural design guidelines that must be followed when building with Kee Klamp pipe fittings. These can be found in the "Technical Details" section.

Features & Benefits
Turn Key Safety Solution
Steel pipe is an inherently efficient structural component, but there's difficulty in quickly forming structures and joining components together. There is zero flexibility in installation as threaded pipe must be supplied in set lengths, and labor intensive welding requires a highly skilled workforce, and specialized equipment. This is when Kee Klamp® can be used, and its flexible engineering principle and various range of product provides many benefits.
Kee Klamp® Features

No welding or threading
Galvanized for long lasting protection
Recessed screws for a smooth look
Large set screws resists thread stripping
Schedule 40 Pipe sizes 1-1/4” - 2”
Specifying & Install
Diagrams are shown for each fitting showing entry of pipe, a table of dimensions and a definition of use adjacent to its appropriate Type number (10, 15, 20, 25 etc.).
Alongside the Type number is a code (4, 5, 6, 7, etc.) relating to the outside diameter of the pipe for which the Kee Klamp fitting had been designed. The relationship between the Kee Klamp pipe reference and standard pipe outside diameter is explained in the aforementioned chart.
Contact our experts to get the best solution. The ultimate responsibility for selecting the correct fitting for an application must lie with the customer, and our experts can help answer questions.
The customer should also ensure that the existing structure to which the Kee Klamp construction is being secured, is of sufficient strength to support both the self weight of the Kee Klamp construction and the imposed loads applied, including wind loads, snow loads, and any other superimposed loads.
Metric Beam Load Table
For uneven load distributions or single spans, the required pipe size must be determined by standard bending moment calculations assuming a Kee Klamp joint to give a simply supported beam. The table shown below gives an indication only of the safe load uniformly distributed, in kg, that may be carried per shelf consisting of front and back pipes when used as continuous beams. Recommended set screw torque: 39 Nm.
At loads greater than 900 kg, consideration must be given to grub screw slip.
Metric Upright Load Table
This table gives an indication only of the safe load, in kg., that may be carried between the above restraints by single pipes to BS 1387 (ISO 65) when used as uprights. Loads listed under 'A' columns refer to those loads that are obtainable according to schematic 'A', and loads listed under 'B' columns refer to those loads that are obtainable according to schematic 'B'. Schematic 'B' details a racking system that is mechanically affixed to the surface on which it stands whereas schematic 'A' details a free-standing racking system. Recommended set screw torque: 39 Nm
Safety Information pertaining to the proper use, care, and assembly of Kee Klamp fittings. It is critical to review this information before and during the use of Kee Klamp fittings.
Exhaustive tests on samples of standard size 7 Kee Klamp fittings were performed by an independent research laboratory. The purpose of the test was to evaluate the use of either standard set-screws or self-locking set screws.
A "Tee" section test assembly was made using three 300mm lengths of galvanized 1 ¼" standard pipe held together by a socket Tee fitting (Type 25-7). The vertical leg of the test assembly was supported in a standard railing flange (Type 62-7). The completed assembly was then rigidly attached to the vibration table.
The test assembly was initially assembled using standard grub screws and tested in the configuration. The standard grub screws were then replaced with self-locking grub screws and the tests repeated.
The test was conducted on a Ling 667 kg Electromagnetic vibration table.
The table was programmed to perform a resonance search between 25 and 350 Hz. The following table details the resonant frequencies that were recorded.
During the resonance search amplification factors, Q, were measured at each resonant frequency, the point of reference being the end of one horizontal pipe. The table was then held at one of the resonant frequencies, set in motion with a controlled acceleration level of 4g, and run for a period of six hours. This was repeated for three more resonant frequencies in descending order of "Q" factor.
During the twenty-four hours of vibration at the four resonant frequencies above no signs of loosening with either type of set screw occurred.
