Box sealing system DS 90 / 74 mm

The box sealing system DS 90 / 74 mm for cables, cable bundles and conduits. The fire-proof and smoke-proof box sealing is quick and easy to install and can also be retrofitted on cables and conduits. The easy-to-fit product offers certified safety and ensures the fire resistance class of the wall (EI90).

Secure, visible, certified fire sealings
For wall feed-throughs and entries
Automatic sealing of the joints and gaps between cables - no filling and smoothing
Non-destructive retrofitting
For cable bundles or individual installation conduits

Examples of use

Use the two-part box sealing system DS 90 / 74 mm to create wall entries and feed-throughs.

Horizontal and vertical arrangement with a centre distance of 91 mm is permissible.

The box sealing system DS 90 / 74 can also be used as a spare seal (empty).

The sealing can accommodate conduits of up to M40.

Populating the sealing system

The box sealing system DS 90 / 74 mm provides space for single cables and bundles up to full population.

By choosing individual configurations, power and communication cables can be separated into groups.

The box sealing system DS 90 / 74 mm can be used with all standard sheathed cables currently found in Europe.

Spare sealing, conduits up to M40 and combination of NYM cables.

Technical information

For use as a spare sealing (empty) for future installations.

Self-explanatory installation based on the tried-and-tested cavity wall box principle.

Easy insertion of the sealing cylinder into the installation opening.

Automatic room separation - no gaps or filling of joints.

Non-destructive retrofitting of individual cables

Loosen the sealing element by turning it a quarter of a turn and open it.

Open the sealing element and remove it.

Insert the new cables.

Place the sealing element around the cable, close it and secure it with a 1/4-turn clockwise.

Installation

The box sealing system DS 90 / 74 mm consists of two parts which easily fit together.

Cut an installation opening using a Ø 74 mm cutter (e.g. PROFI, Art. No. 1081-20).

Place the two-part sealing cylinder around the cables and press together.

Press the sealing cylinder into the installation opening.

Fasten by tightening the screws (same procedure as for cavity wall boxes).

Place the sealing element around the cables and close it.

Place the sealing element on the seal cylinder and secure it with a 1/4-turn (bayonet fitting).

After installing the sealing, apply the identification tag.

This ensures sealing and the necessary room separation.

Installation of box sealing system DS 90 / 74 mm in masonry

Cut an installation opening depending on wall thickness with an 74 mm diamond grinding head or with a core drill.

Press the sealing cylinder into the installation opening with plaster, mortar or quick cement and feed the cable through.

Place the sealing element on the seal cylinder and secure it with a 1/4-turn (bayonet fitting).

Horizontal and vertical arrangement with a centre distance of 91 mm is permissible.

Note

Cable population of the box sealing system DS 90 / 74 mm with all sheathed cable types recognised in Europe e.g. installation cables, data cables, telecommunication cables or fibre optic cables, as wiring bundles or as individual cables. Cable bundles can be populated up to Ø ≤ 40 mm, with a maximum diameter of ≤ 15 mm for a single cable. Single cables can be used up to Ø ≤ 21 mm.
