The approval-compliant and safe installation of a fastening always requires the use of the appropriate application-relevant mounting accessories. Only in this way can it be ensured at the end of the application and final load application that the fastening also holds as promised and that there are no discrepancies. Chemofast provides its customers with all-round support and therefore offers all application-relevant mounting accessories with the fastest possible availability. The accessories are specifically tailored to the core competence, namely chemical and mechanical fasteners, and offer manual and pneumatic squeeze-out equipment for injection mortar systems as well as additional static mixers, sieve sleeves for masonry applications, backfill nozzles for air bubble-free backfilling of boreholes, and mixer extensions in various sizes for the proper and approval-compliant backfilling of a borehole even at longer setting depths. The other side of the mounting accessories are the cleaning products. The installation of a strong fastening requires the meticulous cleaning of the borehole. Only in this way is it possible for the fastening product to develop its full performance in the end. However, with the help of Chemofast's cleaning accessories, consisting of a variety of cleaning brushes, squeeze pumps, suction bells as well as certain attachments and extensions, the flawless borehole cleaning and preparation should work confidently.
