AL Modular System · Connection elements
Corner bracket
The corner bracket closes the corner of a cube structure with three profiles, square or with rounded section, of the same size: it screws onto the profiles with self-tapping screws, without drilling or tapping. On the corner you fit a spherical or cube cover cap, which protects against knocks and injuries and keeps dirt out.
Why choose it
Three-way corner
Joins three profiles of the same section at the corner of a structure.
Self-tapping screws
Screws onto the profile without tapping: the screws are included.
Protected corner
With the spherical or cube cover cap the corner has no sharp edges.

No: the code includes the corner connector and screws. The spherical or cube cover cap, in signal grey or black ESD, is ordered separately: tell us which shape you prefer and we will give you the code for your size.
Both join profiles of the same section without machining. The corner bracket always joins three profiles and is closed with a spherical or cube cover cap; the cubic connector comes in 2- or 3-way and the set already includes screws and cover caps.
The one of the corner bracket you are fitting: R20x20 for profiles with slot C6, R30x30 for those with slot C8, R40x40 or R45x45 for 40 and 45 profiles with slot 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.
