Roxtec Cable Transit & Sealing Guide
Roxtec Cable Transit & Sealing Guide
A Roxtec multi cable transit (MCT) seals many cables and pipes through one opening in a wall, floor, bulkhead or cabinet. This guide explains how Roxtec frames, RM Multidiameter modules and wedges fit together, and when to choose ComSeal, EzEntry, sealing kits or round seals instead.
Telenco UK supplies the Roxtec range to trade customers across the UK, with core RM modules, frames and wedges held in stock.

What Is a Roxtec Cable Transit?
A traditional cable gland seals one cable per hole. A Roxtec transit seals a whole group of cables and pipes of different sizes in one opening, and can be re-opened when cables are added or changed.
Every modular transit has four parts: a frame fixed into the opening, RM sealing modules fitted around each cable, stayplates between each row of modules, and a wedge that compresses everything into a tight seal against water, dust, gas and pests.
Roxtec Multidiameter™ modules have peel-off rubber layers, so one module adapts to a range of cable diameters on site.

Which Roxtec Product Do You Need?
Start with where the cables pass through and how many there are.
Frames
Roxtec frames hold the modules. GH frames have a pre-drilled flange for bolting to flat structures; G6x2 and G6x3 frames have two or three 120 x 180mm openings for larger cable runs; CF16 and CF32 frames suit cabinets.
RM modules
RM modules seal each cable. Sizes include RM15, RM20, RM20W40, RM30, RM40 and RM60, plus BG B modules for bonding and grounding.
Wedges & stayplates
Wedge kits and stayplates compress and support the modules. Add solid compensation modules to fill spare space and keep capacity for future cables.
ComSeal
Roxtec ComSeal seals cable entries into enclosures, cabinets and terminal boxes. The ComSeal 16/16 takes up to 16 cables or pipes and is rated IP55.
EzEntry
Roxtec EzEntry seals have lightweight composite frames that fit directly into standard openings, in six sizes for 4 to 32 cables, rated IP66/67.
Kits & round seals
Sealing kits include Ex, ES and BG B kits, HD pre-configured transits and CRL seals. For a single cable or pipe, see SPM and marine seals.

How to Choose Roxtec Modules & Frames
1. List your cables. Measure the outer diameter of every cable and pipe, and allow for future additions.
2. Pick module sizes. Choose the RM module whose range covers each cable – for example the RM30 for 10–25mm. Peel layers until the module fits.
3. Choose the frame. Size it to hold all the modules, and pick galvanised steel for general use or AISI 316 stainless for marine, offshore and corrosive sites.
4. Complete the transit. Add a wedge kit, stayplates, compensation modules for spare space and Roxtec lubricant for installation.
Need a special function? Use an Ex kit for hazardous areas (ATEX and IECEx), an ES kit for EMC, or a BG B kit for bonding and grounding.

What is a multi cable transit (MCT)?
A multi cable transit is a sealed opening that lets several cables and pipes pass through a wall, floor, bulkhead or cabinet. Roxtec transits use a frame, adaptable rubber modules and a compression wedge.
What is Roxtec Multidiameter™?
Multidiameter™ modules are made of peel-off rubber layers. Removing layers adapts the module to the cable or pipe diameter on site, so fewer module sizes need to be stocked.
What is a Roxtec gland?
"Roxtec gland" is a common name for a Roxtec cable entry seal. Unlike a standard gland, one Roxtec seal can take many cables of different sizes. See our cable gland seals.
ComSeal or EzEntry?
Both seal multiple cables into cabinets. EzEntry has a composite frame for standard openings and is rated IP66/67; ComSeal is rated IP55 and comes in aluminium or AISI 316.
What do Ex, ES and BG B mean?
Ex kits are for hazardous areas and support ATEX and IECEx compliance. ES kits add EMC protection. BG B kits provide electrical bonding and grounding.
Can I add cables to a Roxtec transit later?
Yes. Release the wedge, swap a compensation module for a sealing module sized to the new cable, then re-compress the transit.
Where can I buy Roxtec in the UK?
