Wall-recessed code tube for a key that must always stay on site
The Kruse code key tube is a stainless steel tube that is recessed into the wall. It holds a key or access card that has to remain available without handing it to someone each time, for example for home care, cleaning, maintenance or as an emergency key. Anyone who knows the four-digit code can open the tube.
Key strengths
- Discreetly recessed: the tube is bonded into the wall, only the code lock remains visible.
- Mechanical code lock: works without battery or power connection; you set the code yourself and change it whenever you like.
- Self-scrambling code (CODE 70 SKG**): the digits are scrambled automatically on opening, so nobody can forget to scramble the code.
- Spacious tube (CODE 70 SKG**): room for several keys up to about 100 mm or an access card.
- SKG**-certified locking insert (CODE 70 SKG**), with the cover fitted.
Two models
The CODE basic (Ø 51 × 147 mm) is the simple version for one key up to 65 mm. The CODE 70 SKG** (Ø 73 × 172 mm) is the larger version, with automatic code scrambling and SKG** certification; for this certification the cover must be fitted. Both tubes are made of 1.4301 stainless steel, with a die-cast zinc code lock.
Installation
The key tube is placed in a core-drilled hole (Ø 56 mm for the CODE basic, Ø 77 to 80 mm for the CODE 70 SKG**) and bonded with mounting adhesive, angled slightly forward so condensation can drain. The Kruse installation instructions are in the downloads.
