The HDE and HDM dispensers allow for fast mortar injections without great physical effort at construction sites. They are used together with the pollutant-free Hilti injectable mortar and firestop foams. Both dispensers feature volume control for accurate hole filling and an automatic pressure-release mechanism that reduces mortar consumption and wastage. The ergonomic design ensures effortless dispensing even in deep anchor holes. Particular attention has also been placed on the safe operation of the devices. Self-explanatory colour coding virtually rules out the risk of confusing system components.
