Benefits for the architect/specifier
- The faint shadow joint between the lever handle and rose/backplate means that the two components appear to be one unit.
- The high-quality Satino surface finish satisfies exacting requirements in terms of the visual quality of the furniture.
- With all roses and backplates having a consistent projection of just 9 mm, all doors can be provided with an integrated, high-quality appearance.
Benefits for the trade/distributor
- Modular system means less storage space requirement.
- Variety of square section spindles to fit different door thicknesses –eliminates the need for ordering separate furniture sets for each major increment.
- Identical intervals for screw and spindle lengths to simplify stocking.
- Rated as category of use grade 4 according to EN 1906, OGRO fittings are also readily suitable for heavy-duty/high-frequency applications in project builds.
Benefits for the installer/fabricator
- The return springs ensure that the lever handles will not "droop" even after years of constant use, instead always being returned to their horizontal rest position.
- The return springs are non-handed, avoiding the problem of mistakes during assembly and installation.
- OGRO door furniture sets are simple and quick to both fit and remove, without the need for special tools (Click&Go system).
- The Click&Go system ensures fast and easy installation, thus saving time and money.
- With the OGRO roses and backplates pre-fitted to the handles, there is no time-wasting application of protective adhesive strips to the handle neck. This is necessary in the case of conventional lever handle sets to ensure surfaces are not damaged.
- Extended support lugs on the roses/backplates mean that larger door thickness intervals (15mm) can be accommodated with the same screw length.
