Under the bonnet of a TS3000V – how to adjust the power, closing speed and latching action.

We looked under the hood (or slide plate to give it the correct name) of a GEZE TS3000V door closer to photograph the fitting holes and adjustment screws, here’s what you’ll find there.  Its very similar to the TS2000NVBC  but they are not interchangeable with each others arms & guide rails because the spindles are different, they’re hexagon on the TS3000, but splined on the TS2000.
