Install teams pick Viokef when rough-in needs to be repeatable from room to riser. The catalogue keeps geometry consistent (Ø68 mm drywall cutouts, 60 mm device screws, 71 mm multi-gang pitch), offers CPR/LSZH options where routes demand them, and publishes torque/strip windows on the parts you actually touch—so first-fix and handover tests land without improvisation.
For masonry, drywall, or mixed substrates, viokef installation materials cover flush and surface back boxes in 40/50/60 mm depths, junction/pull boxes from 80–240 mm, and multi-compartment trunking matched to device plates. Knockouts accept 16/20/25 mm conduits with membrane or threaded entries; divider kits preserve SELV/mains segregation. Where fire paperwork matters, LSZH grades (IEC 60754/61034) and CPR EN 50575 classes up to Cca-s1,d1,a1 are available, with printed metre marks and DoP references. Publish a simple matrix—wall type, depth, entry, CPR/LSZH—and crews stop guessing on night shifts.
Bathrooms, housekeeping points, and plant rooms need IP that survives maintenance. Gasket rings lift ingress to IP44 when the mounting orientation is observed; compression glands are sized to jacket Ø so strain sits on the clamp, not the terminal. Adapter plates and spacer rings (2–10 mm) correct proud plaster and legacy cutouts; repair collars hide chipped edges without moving the trim line. List viokef installation accessories by room type (wet, guest, corridor) with the correct thread set and you’ll avoid last-minute store runs.
Cantilever consoles, trapeze hangers, universal wall brackets, and drop rods (M8–M12) are rated to IEC 61537 deflection criteria and supplied in pre-galv, HDG (EN ISO 1461), or stainless for harsh zones. Side loads for channels/trays are documented; seismic notes specify sway bracing and anchor embed depths. When a run crosses mixed substrates, viokef mounting systems keep hole patterns and fastener lengths consistent, so you can repeat spans without recalculating every bay.
Method statements are simpler when the platform is predictable. Device supports keep terminals accessible for probe tests; multi-gang bars maintain 71/71/71 mm pitch so scene plates and data stay level; divider heights preserve Cat-rated bend radius behind mixed plates. For boards and small DIN housings, neutral/earth bars, end-stops, and label windows are standardized—giving viokef electrical installation a single torque/strip rule across floors (typ. 0.4–0.8 Nm, strip 8–10 mm on devices; always confirm the label).
Panels and canopies use loop-through blocks with separate bays for L/N/PE and dimming lines, plus bridges for rows. Spring and screw terminals accept 0.5…2.5 mm² Cu; ferrules fit cleanly; test points are visible after fit-off. Crews catalogue viokef wiring components by pole count, conductor range, and rated torque so pull tests land first time.
Rigid PVC/LSZH conduits serve interiors; steel or stainless variants add impact resistance and EMC. Diameters 16–63 mm with IP54–IP67 compression glands cover most routes. Respect bend radii (≥6×OD for power, ≥10×OD for data) and solvent-weld or thread where movement or cleaning is expected. Schedules that name viokef conduit systems should fix material, IP class, and maximum pull lengths between draw boxes.
Surface/flush enclosures with DIN rails, earth/neutral bars, through-door handles, and gland plates arrive pre-drilled so devices land square. Blanking plates, end-stops, and marker strips keep small assemblies auditable. Technicians keep viokef installation hardware grouped by door swing, gland thread set, and spare DIN pitch to make later additions painless.
Boxes/enclosures EN 60670-1; trunking EN 50085; conduits IEC 61386 (compression/impact/bend classes). Ingress IEC 60529 (IP20 default; IP44/IP55 with gaskets; IP65 on outdoor junctions). Fire/smoke CPR EN 50575 with DoP; flame IEC 60332-1-2/-3 where specified; LSZH per IEC 60754/61034. Geometry: 60 mm device screws, Ø68 mm cutouts, 71 mm multi-gang pitch. Typical terminal windows 0.5…2.5 (devices) up to 25 mm² (feeders); torque and strip printed on parts.
Hotels/offices: multi-compartment channels feeding power/data on one grid; IP44 sets in wet areas. Education/healthcare: LSZH bodies, antibacterial fronts; tamper-proof lids. Logistics/plant: IP55 junctions on block walls, steel conduits and HDG supports where impact/EMC demand it. All pieces align with Viokef luminaires and device plates, so OD windows, bend guides, and trim lines match.
Expect request-specific pricing, fast quote turns by EAN/MPN, and live EU stock before crews are scheduled. The portal shows current lead times, tracks shipments, and offers downloadable price lists with validity windows you can plan against. Trusted clients can use post-payment terms up to 30 days. We consolidate consignments so boxes, channels, conduits, brackets, fasteners, glands, terminals, and labels arrive kitted by riser or area; an account manager cross-checks spans, finishes, CPR/IP classes, segregation rules, torque/strip notes, and thread sets against your documents—keeping deliveries immediately usable across France, the Baltics, Germany, Spain, Italy, Belgium, and the Netherlands.
