Retaining ring
When you fix panels and sheets to profiles with screws, the retaining ring keeps the screw in the panel hole even when it is unscrewed: no lost screws during maintenance or replacement. It can also be added to structures already assembled. If you use it with the S bracket, check the highest bearing point of the panel.
Why choose it
Captive screw
The screw stays attached to the panel when you unscrew it.
Also retrofittable
You add it to panels already mounted.

Yes. With the S bracket check the highest bearing point of the panel, because the ring is 1 or 1.5 mm thick.
The bracket locks the Variofix with a snap fit, without tools. Alternatively, you fix it with an M6 screw and square nut: in that case the retaining ring keeps the screw attached to the panel, as required by the Machinery Directive 2006/42/EC.
The one matching the thread of the screw that fixes the panel: M4, M5 or M6. The inner diameter is 3.4, 4.5 and 5.5 mm.
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.
