Short screw for cast iron grate with transverse crossbars ACO GALA G100 08373

Protection for Cast Iron Grate in the ACO Gala System

The primary function of this component is to securely and permanently fix heavy cast iron grates in ACO Gala G100 linear drainage channels. Unlike standard solutions, this specific screw has been specially designed for channels with low construction height, making it an essential component when installing the 6 cm high version (type EK37). Thanks to its shorter thread length and head, the screw fits perfectly into the available space in lower drain boxes, without protruding above the grate surface or compromising the aesthetics of the pavement.

A key function of this accessory is theft and accidental removal protection for the grate. In areas with high pedestrian traffic, such as sidewalks, school courtyards, or platforms, loose grates pose a safety hazard to users. The screw prevents the grate from being removed without the appropriate tool (Allen key or socket wrench), effectively hindering unauthorized access to the channel interior or theft. This solution is particularly important in public areas where the risk of vandalism or accidental damage to infrastructure is higher.

Application and Compatibility

The product is dedicated exclusively to the ACO Gala G100 system with cast iron grates (load class C250). It should be noted that not every screw type fits every channel – the choice between the short and long version depends on the installation depth. The short version described here is intended solely for channels with a construction height of 6 cm (low version EK37). For comparison, the long version is used in channels with greater height (e.g., 15 cm and more), where a longer fixing length is required.

Therefore, when planning a renovation or new installation, it is advisable to carefully check the type of channel being installed:

• If working with a low channel (EK37), it is necessary to use this short screw to avoid the component protruding above the pavement level.
• In the case of deeper drain boxes, the standard long screw should be used, which ensures proper clamping in a larger installation space.

Installation and Practical Benefits

Installation is based on a simple screw mechanism that allows for quick and precise clamping of the fixing crossbar to the grate frame. For the installer, this means flexibility – the system allows for easy disassembly for channel cleaning or servicing, provided the appropriate key is available. For the end user, this guarantees stability: even with intensive pedestrian traffic or passage of light vehicles (e.g., bicycles, carts), the grate remains in place, without causing noise or creating unevenness on the pavement.

It is worth noting the material of manufacture – the screw is compatible with the cast iron elements of the system, ensuring resistance to galvanic corrosion in the humid environment typical of linear drainage systems. As a result, the entire structure maintains its properties over years of operation, minimizing the costs of subsequent repairs or replacement of damaged fixing elements.
