The X-Chair is an easy-to-use ferrule chair, developed to locate ‘near face’ ferrules in precast and tilt-up panels. The uniquely designed X-Chair accommodates all standard X-Foot and and round 96mm high ferrules. The X-Chair will cater to most third party round ferrules. The design has an in-built cross support and integral centre spigot to accurately position the ferrule to shop drawing locations.
