Grand and Upright Piano Hammers
We manufacture over 500 different types of hammer heads in various sizes, with or without underfelt, in different core lengths and shapes. We also manufacture according to individual customer specifications. For branded instruments we make the hammers with their corresponding original felts. We are also able to recover hammers to the highest possible standard.
You have the choice, Renner has the range: Choose from levers with or without, a spring adjusting screw, adjustable jack button or with or without suspension springs fitted. Choose from a range of heels, but as always with exemplary Renner quality and precision.
Renner hammer shafts are made of white beech – an extremely hard but relatively light wood. The cross sections of the shafts decrease from the low to the high sounds in order to ensure optimal sound properties and playing sensation. The Renner Portfolio encompasses hammer shafts for numerous brand name upright and grand piano manufacturers, in different models.
The felt determines the quality of the damper. Renner exclusively uses specialist felts from the best felt manufacturers for their grand and upright piano dampers. We can supply coloured under-felt of your choice, stitched treble dampers, two, three or four part damper bodies. We have what you need.
