The Item MB system has a number of excellent alternative solutions that can provided for perimeter guarding requirements.
The Item MB system, available from Machine Building Systems, has a number of excellent alternative solutions that can provided for perimeter guarding requirements Most cell guards consist of a series of extruded aluminium profile posts, bolted to the floor, and removable framed panels

Ball feet allow machine guards to be floor mounted
The Item adjustable ball foot mounting has been designed for where cell guards or enclosures are floor mounted, rather than fitted to a machine structure, and have to accommodate uneven floors
Rebate profiles help create dirt-tight frameworks
Rebate profiles in the Item range of building components can be used for mounting a wide selection of panel elements.
The Item system has a number options available for the component parts.
The post type will usually be line-8 80x40 light profile but can also be line-6 60x30 profile as a lower cost option if slightly strength is acceptable.
Floor-fixing methods can vary by using, amongst other things: adjustable ball feet which fit to either line 8 or line 6 posts, compensate for uneven floors and eliminate the need to accurately drill fixing holes in the floor; height-adjustable folded steel feet which also compensate for uneven floors and are a robust design, particularly effective at absorbing impact; or adjustable stand feet comprising height-adjustment, compensation for uneven floors and having additional side-braces as an option where lateral support is required.
Panels can be either black powder-coated welded steel or woven aluminium/steel mesh, or transparent polycarbonate, acrylic or PET-G.
All lift off panels need to be framed and, as expected, there are a number of options here too: clamp profiles are available in two sizes and with different panel clamping methods.

Plain faced framework parts look and stay clean
The 20 x 20mm profiles in the Item line 5 range offers plain faced sides adjacent or opposite to each other, with either two or three conventionally grooved sides
Neater frameworks use concealed fixings
The neatest and most efficient way of connecting accessories or dissimilar profile lines together in the Item range of building components is by utilising concealed fixings.
Clamp-profile 8 is a 40x40 extrusion with a deep slot for locating panels.
It incorporates screw-clamped L-strip which is ideal for fixing steel mesh panels as this stops flexible mesh panels from sliding under impact.
Alternatively, an economy 40x40 clamp-profile may be selected which uses a simple steel clamping-strip.

This is especially good for fixing aluminium mesh panels for similar reasons, or lip-seal can be used for locating solid panels as this is a particularly cost effective method.
Panels up to 8.5mm thick can be fitted.
Clamp-profile 6 is a light-weight 30x30 extrusion.
Options are as outlined above for line 8 with panels up to 6mm thick being accommodated.
These framed panels now need to be attached to the fence posts and there are a number of hanger types available.
Clamp-profile hangers are integrated with clamp-profile fastening sets.
These can be used with line 6 or line 8 options and simply hook over the hanger which is then secured by simple adjustment with a spanner.
Hanger 6-8 can be used for a combination of line 6 and line 8 posts and panel frames and the fitting position can be varied to suit the customer's needs.
Final fixing is achieved with a simple grub screw.
Hanger 8 is a particularly robust design for panels that need to be removed regularly.
Variable fixing positions are possible with final securing by cap-head screw.
All of these methods are ideal for one-man assembly: the panels are positively located even before the final fixing operation, making the on-site commissioning of complex machines where access is frequently required but the machine must still be kept safe, very easy.
For protective fences where panels need not be removable the Item Protective Enclosure System is the perfect solution.
It comprises deep-slotted line 8 profiles allowing the fixing of mesh and solid panels and process-free fastening techniques are used to save on machining costs.
A number of different feet are available although the adjustable stand-foot provides a particularly elegant solution, and modular hinges provide a number of alternatives for incorporating opening doors.
Where budgets are particularly tight, the Item Dual-Rod Mesh System provides the answer.
This system uses a very simple method of safety fence construction whereby line 6 or line 8 posts are fixed to the floor and very rigid 8mm welded-steel panels are attached by means of a very versatile hanger which has a number of features: a slotted design allowing for lateral adjustment; rotating locators which compensate for misalignment of posts; one hanger can used for fixing two panels; the rotating feature doubles up to be used as a hinge; 25mm mesh size and a lower cost 50mm mesh size are both fitted using the same hanger.
