• If the holes are on an outward bend (see diagram at the end of the page), when marking the holes, reduce from 3 to 5mm
the standard distance indicated by the drilling template. On an outward bend, the fabric covers more of the pole (See fig.
B) than if it is a straight line. This is why we reduce the spacing between the poles by a few millimetres. At the time of
making the holes, tilt the drill from 2º to 4º towards the outside of the pool with the aim of providing poles with a slightly
outward incline. Said incline will guarantee that the net has the optimum tension on the superior part of the barrier. If the
bend is not too pronounced, 2º is probably enough; if, on the contrary, the bend is more noticeable, then 4º (See fig. C).

On an outward bend, the fabric covers more of the pole than if it is a
straight line.
• If the holes are on an inward bend (see diagram at the end of the page), when marking the holes increase from 3 to 5
mm the standard distance indicated by the drilling template. On an inward bend, the fabric covers less of the pole (See
fig. D) than if it is a straight line. This is why we increase the spacing between the poles by a few millimetres. At the time
of making the holes, tilt the drill from 2º to 4º towards the inside of the pool with the aim of providing poles with a slightly
inward incline. Said incline will guarantee that the net has the optimum tension on the superior part of the barrier. If the
bend is not too pronounced, 2º is probably enough; if, on the contrary, the bend is more noticeable, then 4º (See fig. E).
FIGURE D
INWARD BEND
FLANGE
When the bend goes inwards, the fabric covers the pole slightly less than
if it is a straight line, so there is a need to increase the space between the
poles by a few millimetres.
The inclination of the poles, depending on the bend, can help
achieve the optimum tension on the superior part of the net.
