## Summary description

FISCHER 557732 DuoSeal screw anchor set (2 pcs) with 8 x 48 mm specification and stainless steel A2 screw compatibility. Designed as a combined wall plug and screw anchor for secure fixings in masonry and concrete, it provides sealed anchoring and reliable load transfer for fixtures, fittings and small structural attachments.

## Long description

The fischer DuoSeal is a two-component nylon plug with an enclosed stainless steel screw, designed to seal drill holes in wet areas without needing any additional sealing compound. Independently tested by the relevant testing institute, the system provides watertightness in accordance with ETAG 022 and DIN 18534 up to water exposure class W3-I. The DuoSeal is intended for use in commercial, private and public wet areas that are frequently exposed to splash water and temporarily accumulated water; national regulations on the use of plugs in wet areas should be observed.
Advantages
The DuoSeal seals the drill hole directly, eliminating the need for separate sealing materials and simplifying installation. Its approval to ETAG 022 and DIN 18534 up to W3-I confirms suitability for many wet-area applications. The two-component design provides higher load values and stability, while the plug can be driven in quickly and easily by hammering. The enclosed screw is compatible with the plug and intended to maintain the watertight connection.
Suitable for
Sealing and anchoring in bathrooms, shower rooms and wash areas
Commercial wet rooms such as hotels, restaurants and public washrooms
Temporary water exposure zones like splash areas and damp walls
Use in various base materials including concrete, masonry and solid substrates
When it may not be suitable
The DuoSeal is tested and approved up to water exposure class W3-I; it may not be appropriate for situations requiring higher water exposure classes or continuous permanent submersion. Also, local national regulations and sealing standards can set additional requirements for certain installations, so the product may not meet those specific rules without supplementary measures.

How to use
Drill the hole to the correct diameter and depth for the DuoSeal plug and clean the hole of dust. Insert the nylon plug into the drill hole and hammer it in until flush with the surface. Insert the enclosed stainless steel screw and tighten to the required torque to secure the fixture; the combined plug and screw assembly creates the watertight seal. Follow national installation rules and the manufacturer’s torque guidance where applicable.
What to consider before purchase
Verify that water exposure of the installation does not exceed class W3-I
Check local and national regulations for fixation in wet areas and any required additional sealing
Confirm base material compatibility and correct drill diameter for the plug size
Ensure the enclosed screw material and length suit the intended fixture
Usage recommendations
Use the fischer DuoSeal with the enclosed stainless steel screw and observe national sealing regulations for wet rooms; clean the drill hole before installation and avoid applications beyond W3-I without further sealing measures.
