We offer both our Roost Maternity Bat Box and Large Colony Bat Box as either single boxes or double boxes mounted back to back on the same pole. The back to back boxes have the advantage that the two boxes will differ in solar gain and resultant thermal regimes. Bats can then choose the box which offers the optimal conditions and are likely to vary which box they use through the year.To securely install your Pole Mounted Bat Box usually requires around 1m of the pole to be buried below ground, however we would always advise you consult your builder or structural engineer as ground conditions vary from site to site. For ease of installation and shipping, the pole will be dispatched separately from the bat box and bracket. Apart from erecting the pole, the only tool needed is a spanner (or a screwdriver for the metal band version) to fix the boxes onto the pole.Features:Ideal solution when no suitable building or tree is available to mount a bat box.Enables the bat box to be placed in the optimum position.Comes as standard with a 4, 5 or 6 metre metal pole or banding to fit to your own pole.Choose between Roost Maternity or Large Colony Bat BoxChoice of a single box or two boxes back to back.Specifications:Pole: 4m, 5m or 6m pole; 76mm diameterBox Materials: Exterior Grade Plywood with ceramic insertsBox Construction: Panels stapled together with surface sunk staples.Finish: External surfaces treated with water-based non-toxic non-volatile wood treatment, with active constituent natural borate mineral salt.Entrance: 17mm wide slot.Internal: 3 internal crevices approximately 20mm wide with 3 ceramic inserts.Access: Removable roof, secured with 1 screw.Fixing: Rail/screw/clip fixing system for attaching Box to PoleDimensions and WeightSingle Box Dimensions: Overall height: 49cm, Overall width: 26cm, Overall Depth: 13cm.Box 6.6kg; 28kg (5 metre).
