E‑1 is the main structural joint. Two joints allow the combination of two pipes at a right angle. E‑1 is the main assembly joint used in building many different structures. It is recommended to keep enough of this basic joint in stock.
E‑1C is used when boxes or similar slide along the pipe, where a combination of two joints type E‑1 would interfere with this sliding. E‑1C is used in connection with guides or slide pipe or similar. Do not use E‑1C as a substitute for E‑1.
E‑2 and E‑3 is used to create a right angle, to ensure that a structure is square. It is an important and very strong joint assembly. If this combination is not used on at least two corners of an assembly then the structure may become unstable.
This combination of E‑4 and E‑2 is often used in larger assemblies where there are several sections. It ensures that all parts are square and stable. In most cases they form the outer edge of a construction similar to the ES‑2 joint combination.
A joint combination consisting of two E‑4 joints is the best way to assemble pipes crossing each other. Typically, the continuous pipe is used for the vertical, the pipe sections for the horizontal. For example, with this connection several shelves of a rack can be built.
Two H‑20 joints and a GAP-12 plastic sleeve are attached by the mechanics similar to the ES‑4 combination and result in a hinge joint, e.g. as for a door cabinet, as a flap or a locking lever. The GAP-12 plastic sleeve must be ordered separately.
Four E‑2 joints are sometimes used at the centre of a larger assembly. It is a convenient and secure way to fix converging pipes. This combination stiffens the application and provides greater rigidity and stability.
Two E‑6 joints form a crossover joint assembly. This not a main structural joint. It lacks the strength of the combination made of two E‑4 joints but is often more convenient for certain purposes. It is often used to support panels or a work surface.
Similarly to E‑1C, E‑6C is used in connection with guides or slide pipe, it provides a crossover possibility without the joint interfering with the box or container. It is of course not as secure as E‑6 so should not be used as a structural joint.
The combination of E‑7A and E‑7B makes a variable angle joint, allowing one pipe to be joined to the middle of another and the angle to be varied. This provides flexibility to the structure. Diagonal bracing is one area where this is commonly used.
Combining E‑7B and E‑7C results in a joint assembly which allows two pipes to be joined end to end at variable angles. This can be combined with E‑12 joint assemblies at the other ends to make a very flexible,mobile part of the structure.
Combining two E‑8 joints is very strong way to join two parallel pipes. This may be to join two structures together or perhaps if a horizontal span needs to be longer than normal and two pipes must be used then the pipes should be joined using this.
The E‑9 double joint is a way to fix two pipes parallel on one other. It is often used in combination with E‑8 joints. This connection is often used in connection with heavy loads, to distribute the weight over two instead of just one pipe.
ES-11 joint combination is often used for handles or grips, many other cases where a rounded corner is desirable either for practical or aesthetic reasons. The tops of work surfaces may be finished in this way. These can be corners on handles or table edges.
The ES-12 connection is fixed by the mechanics similar to the ES‑1 and forms a hinge in connection with the GAP-12 plastic sleeve. This may be used to assemble a door, gate or barrier. The GAP-12 plastic sleeve must be ordered separately.
E‑14 is often used to combine two joint assemblies made with E‑7A and E‑7B or two E‑13A and E‑13B at the head of diagonal bracing sections. This bracket set is used to stut a construction and thus gain a higher stiffness and stability.
Joint combinations of E‑15A and E‑15B are excellent for fixing panels or work surfaces to structures. The panel is then fixed on top of the pipe with screws. This joint can be used to fix pipes to walls or to aluminium profile.
E‑15M‑A/-B joint combination is attached to the pipe similar like E‑15A. It is used on various worktops and lifting systems. Due to their oblong hole, one is more flexible in the attachment in the width. These combinations can also use for panels.
The combination of an E‑15CL or an E‑15-CR joints with the E‑15B allows the installation of worktops or shelves with side walls on vertical pipes: This is a real advantage when space is at a premium. Please always pay attention to pair formation when ordering.
Two E‑16 joints provide a simple method of fixing a panel at halfway across the thickness of the pipe. This combination is often used when the board must be within the structure rather than above it.
This joint combination is used to join two parallel pipes. One pipe is fixed, the other can turn in the joint. This is used to make a gate or barrier, or as above in the case of E‑12, a section of a structure can lift to provide access or passage.
Two E‑18 joints and two GAP-12 plastic sleeves also allow the connection of two parallel pipes, whereby both pipes can be moved in the joints. For example, this combination can be used in folding applications.
Two E‑21 joints can be used to connect tubular plug-in system constructions with aluminium profiles. Of course, this connection combination can also be used as vertical support for panels or for fastening your construction to walls or floors.
This combination allows the pipe system to be fixed to the corner or end of aluminium profile or to the side of a wall or another structure. This type of combination is often used for roller conveyor connections.
This joint combination is similar to the standard E‑1 joint combination but can be mounted over a joint to save space. Thus, double struts can be mounted to stabilize the construction. This allows double struts to be fitted to stabilise the structure or for various other uses.
This joint combination is similar to the standard E‑4 joint combination but can be mounted over a joint to save space. As with the ES-1L joint combination, the construction can be strengthened with a double tube.
