Traditionally, supporters have been able to access any part of the terrace but to allow the iconic ground to operate at its optimum capacity, members are asked to notify the club whether they want to stand in the East (Clubhouse End) or West (Taff End) side of the enclosure.
Changes will take effect from the Guinness PRO14 opener against Leinster and remain in place for the remainder of the season.
Members are asked to fill in the attached form, supplying their membership ID, or call 029 20 302030. In the case that supporters do not get in touch, you will be automatically allocated.
New members will be required to nominate a side of the terrace during the purchase process. Season Memberships are still available and can be purchased by clicking here.
