Frequently Asked Questions about Renz Letterbox Systems
Answers for property planners, management companies and specialist contractors
| Which Renz letterbox system is suitable for a 10-unit apartment building? For a 10-unit property, a modular Renz flush-mounted system from the Individual or R-950 series is recommended – configurable as a 2-column 5-row installation or according to individual compartment layout. Stainless steel V2A versions are recommended for outdoor installation; in covered entrance areas powder-coated steel versions are also suitable. Our sales team advises on the optimum configuration. |
| Do Renz letterboxes comply with DIN EN 13724? Yes – Renz letterbox systems are standards-compliant with DIN EN 13724 and meet the requirements for letter slot opening size, compartment volume and lock security. Standards compliance is particularly relevant for new construction projects, as it is required by building authorities and inspection bodies. Renz provides corresponding conformity documentation. |
| Can an existing Renz letterbox system be expanded retrospectively? Yes – the modular Renz system allows retrospective expansion of existing installations with compatible additional modules, provided the original installation is from the Renz modular system range. When purchasing new systems, it is advisable to plan for the maximum number of compartments required, or to choose an expandable system. Our sales team assists with compatibility checks. |
