Abstract: In a system for converting a synthetic turf surface area from one to another condition which includes a receiving slot below ground level containing marginal portions of synthetic turf products in wedged engagement, the improvement in converting the surface area to another condition wherein one turf product is removed which comprises a removably positioned L-shaped rigid support bearing a yieldable pad for the margin of the remaining turf product after its removal from the slot. The process comprises removing such margin from the slot, inserting one leg of the L-shaped support snugly into the exposed slot and then anchoring the margin under tension over the other leg of the L-shaped support to create a synthetic turf border with respect to the area from which the turf product was removed.
