The structure is made of metal profiles that can be adjusted to the 5 regulatory heights (1,067;
0,991; 0,914; 0,838; 0,762 m), adding a 6th height of 0,686 m (for veteran competitions), by means
of an automatic locking device.
The vertical lifting profiles are smooth and are attached to the PVC top bar by a piece of
polyamide, which at the same time covers the profile of the upper part, preventing the entry of
water. Inside it is housed a spout with a spring to fix the lifting profile.
In the metal base is housed the counterweight, which is made of Steel using an anti-corrosion
treatment and can be adjusted in 6 positions depending on the selected height.
The top bar is made of PVC according to WA standards.
