Quick assembly and sturdiness for the new version of TOP SPIN by Master, the comb hinge made of extruded aluminium

TOP SPIN is Master’s line of extruded aluminium hinges, developed for casement, bottom hung and top hung opening systems. The historic line of hinges has always stood out due to its reliability and durability as well as its great adaptability to various types of profiles, on R-Series and euro groove.

With the new TOP SPIN Art. 3420.72 this year, the company introduces a version that further improves compatibility with euro groove systems with frame groove 14/18 (node A01) and frame groove 13.5/16.7 (node A05). This new comb hinge is characterised by its new and even faster pin fastening system, which is now done using a grub screw.

The new TOP SPIN retains all the main technical features that have made it one of the most reliable and high-performance products on the market. Like all TOP SPIN comb hinges, the 3420.72 is made of extruded aluminium with a stainless steel pin. The quality of the materials and assembly guarantees maximum durability with load-bearing capacities of up to 120 kg for casement openings and up to 200 kg for bottom hung using the additional front screw.

The new comb hinge can also be applied to already installed frames without the need for further machining, and the extruded aluminium flaps also allow for the production of versions with an oxidised finish.


With this upgrade in terms of ease of installation and compatibility with all CE systems, the TOP SPIN line is further strengthened and, together with the TOP RAPID line, completes Master’s range of window hinges, products that are now very popular on the market due to their performance and reliability.
