C-Port Air-Port Utility Pads are made from 100% recycled rubber and designed as a non-penetrating, economical and light-weight support safe for installation on any type of roofing material or other flat surface. Grooved, recessed tray design prevents movement and dampens vibration while providing a solid support for all electrical and HVAC equipment. The proprietary free-flow leg system allows for easy water passage beneath the equipment inhibiting the growth of harmful moss and mould. The UV resistant Air-Port is the perfect long-lasting alternative to roof-damaging heavy concrete curbing and pressure-treated wood blocks. 36 Inches length
