The short trough type is to fix the stone panel with stainless steel pendants. The general slotting of the short slot type is about 100mm. When connecting the stone, the S and E pendants are glued to the stone with special glue. Each stone is placed in 4 such configurations. The lower end of the stone is fixed with an S pendant, and the S pendant is used as the main load-bearing end. The upper end of the stone is fixed with an E pendant, which can support the force on the left side. Common ones are T-shaped pendants and butterfly-shaped pendants, and now there are also aluminum alloy S and E pendants. The through-slot and short-slot pendants can be used universally.
