  • Ceramics
  • Laminate (HPL)
  • Synthetic material

How Keil Anchors work

Drill hole, anchor sleeve and screw lengthmust be matched to the desired insertiondepth and the hanger of choice.Onlythe use of matching parts will make theassembly quick, simple, and safe.

Insert the at the base compressed anchorsleeve, together with the required bracket,into the undercut hole.

Screw in the screw, exerting gentlepressure on the bracket (in order to fix theanchor). The locking ratchets of the screwwill cut into the bracket, securing thescrew.

The anchor sleeve is expanded to itsoriginal dimensions by inserting the screwto a controlled depth, making it sit snuglyagainst the panel in the undercut areaof the drill hole. After the assembly, theanchor will sit in the undercut hole free ofexpansion pressure (i.e. the bracket canstill be rotated with a certain amount ofphysical effort)
