Anti-torsion element for central bolt
An end connection with a central bolt holds well, but the profile can rotate about its own axis. The anti-torsion element is fitted in the slot at the connection and locked with the included set screw: this way the profiles do not rotate. You can add it later too, without dismantling the joint.
Why choose it
No rotation
Increases the torsional resistance of the end connection.
Even afterwards
Added to an already assembled connection.
Set screw included
C8 with set screw M5x8, C10 with set screw M6x12.

When you join two profiles end to end with the central bolt or a quick connector and the connection must withstand moments that would rotate the profile, for example a side-loaded cross member.
With a single central bolt, yes, if the moment is high. To lock it, add the anti-torsion element for slot C8 or C10: it increases torsional resistance and can also be fitted after the connection has been made.
Yes, it can also be fitted later: you do not need to dismantle the connection.
When the joint must withstand torsion: the device increases the torsional resistance of the profiles joined with the quick connector and can also be added later, once the connection is assembled. Available for slot C8 and C10.
It is the width of the profile slot and determines which accessories you use. Slot C6 (6 mm) is for 20 series profiles, C8 (8 mm) for the 30 series, C10 (10 mm) for profiles from the 40 series upwards. Nuts, screws, brackets and cover caps are chosen by slot: each accessory's product page shows the right one.
Yes. You can order the full bar or the piece cut to the length you need: we do the cutting ourselves, in our workshop. Each profile's product page shows the maximum bar length and the minimum cut length.
Look at the moments of inertia Ix and Iy: the higher they are, the less the profile deflects under load. For the same section, “L” profiles are lightened and deflect a little more. For long spans or high loads move to a larger section or a tall profile (e.g. 45x90 instead of 45x45). If you send us drawing and loads, we will check the choice.
The T-nut is inserted from the front into the slot, even in an assembled structure, and positions itself when you tighten the screw: it is the standard choice for fixing accessories. The sliding block withstands higher forces, but normally has to be inserted from the profile end before closing the frame; spring versions stay where you put them.
The simplest way is the bracket, which joins two profiles at 90° with screws and nuts in the slot, without machining. For end, T, 45° or three-way connections there are dedicated connectors, some of which require profile machining as stated on their product page.
Yes, for several accessories (for example cover caps, hinges and nuts) there are conductive ESD versions, indicated in the name or variant. Tell us which EPA area you work in and we will confirm the components to use.
On each product page you will find the MGE catalogue pages to download as PDF, with dimensioned drawings and technical data; the Specifications tab shows the data for the variant you have chosen.
Yes. Send us the parts list or a sketch with dimensions: we give you codes, quantities and cut lengths and prepare the kit with profiles already cut and the accessories.
