Centring sleeve for cylindrical aluminium flagpoles, Ø 100 mm, with anti-twist and remo has the item number 8170.50. The entry-level price is 101,15 € incl. VAT.
This version is intended for pole tubes 100 mm thick. It is made in aluminium.
In the centring-sleeve installation version, a centring ring is firmly bolted to the pole tube at the height of the socket rim. Thanks to precision manufacturing, this centring ring fits into the centring sleeve without a gap; the sleeve's inner diameter is approx. 10 mm larger than the pole tube diameter. The collar of the centring ring closes off the centring sleeve at the top, so dirt cannot get into the ground socket.
The base centring piece, firmly connected to the bottom of the socket, acts as the counter bearing for the pole tube. This design makes the pole tube easy and safe to align and, even after many years, easy to remove again. Centring sleeves are made from thick-walled round aluminium tubes.
In the version with anti-twist and removal protection for cylindrical pole tubes, the centring ring is additionally fitted with a clamping bracket that sits in the pole groove. By tightening an Allen screw set into the collar of the centring ring, the clamping bracket fixes the pole tube in the centring sleeve in any alignment.
When installing the centring sleeve in the foundation, there is no need to consider the later alignment of the poles' hoisting device.
