Surface mounted frames are frames that must be bolted to a wall or steel bulkhead. This may be necessary because cables have to be pulled at an existing location and/or welding is not allowed in steel structures.

Assortment of surface-mounted framesa In contrast to the RGB window, the RGG window is intended to be bolted to a wall (in retrospect). The RGG window is basically the same as an RGB window, in which the flange is provided with holes, which provide space to fix the window to a wall with bolts. The space between the rear of the window and the wall is provided with a waterproof sealant, such as Sikaflex.
The RGG window is also suitable for use on hollow or lightweight walls. In that case, use is also made of a thin, galvanized counter frame, which can be placed on the other side of the wall and falls into the hole provided. The counter frame keeps the intermediate insulation in place and shields the existing hole in the hollow wall at the rear. The window size of the RGG window determines the size of the counter frame. Apart from that, three different depths of the counter frame are available for varying wall thicknesses.
The RGGOK frame is intended for use in existing situations. In essence, it is a surface-mounted frame, which must seal the existing through-hole in a wall or floor. Existing situations often involve cables that may not or cannot be removed, while at the same time there is a transit point that is insufficiently watertight or fire-retardant. Sometimes there is also the need to add a few cables. In all cases, it must be determined with which size RGGOK frame can completely seal the transit space, while at the same time the cable numbers, diameters and positions must be mapped. Based on that inventory, the correct type of RGGOK frame can be determined.
The RGGOK frame has the same internal width as the standard RGB frame (120mm) and is also available in four height units: from 100mm in 60mm increments up to 280mm internal height. In addition, there are multiple windows, where extension in horizontal direction is possible.
RGGOK is supplied as standard in galvanized steel, but it is also possible to order the frames in stainless steel. The RGGOK is fitted with bolt holes (M8) as standard. If desired, a custom hole pattern can be supplied. The required liquid gasket is also available from TTTBV.
The round sleeves, in which an RGP can be placed, are tailored to the various RGP sizes; six sizes are available as standard. Various types are available, both with and without a flange and suitable for welding in as well as for surface mounting. In the latter case, the flange is provided with screw holes. The jacket with flange and screw holes is also available in an open version, for placement around cables or pipes already installed.
The RGSFB is similar to the RGSF, only the RGSFB is provided with screw holes, so that the window (as opposed to welding) can be bolted to a wall. The RGSFB windows can be used in areas where heat (such as during welding) is prohibited, or in situations where welding entails unacceptable risks for the wall in question.
RGSFB frames are supplied as a complete kit, including drilled holes, screws and nuts, body washers and a compound. The latter is used between the flange and bulkhead or deck to ensure a water-tight and gas-tight penetration. The standard measures and weights are in accordance with those of the RGSF. For situations where an RGSF is required, but where the cables are already installed, the RGSFBO is available.
The MCT Brattberg MSR Cable Gland is a pressure-resistant cable gland, tested up to 15 bar, developed for the rapid introduction of cables or pipes in an existing steel wall. In addition to pressure resistant, the MSR cable gland is also A60 fire retardant. To apply the MSR cable gland, only a hole needs to be drilled in the steel wall or floor. No welding is required, which saves a lot of time. The MSR Cable Gland is available in galvanized steel or in stainless steel 316L.
The MSR Cable Gland is available in ten standard variants. Deviating sizes are available in consultation. The MSR Cable Glands range is suitable for cables from 4 to 32 mm. In addition to cable glands for single cables, cable glands for multiple cables (up to 8) are also available.
The ALF box transit is a cable transit to feed a large number of cables dust and watertight on a small surface. All cables are fed through one opening, the penetration being locked with two bolts using an Allen key.
The ALF frames are often used in trains and trams, control cabinets, computer housings, telecommunication houses and industrial installations.
