Psus-a Gen III Locking Back Bolt
The Prudential anti-loosening back bolt installs electrically with zero panel damage. Seismic resistant and self-locking, it safeguards stone curtain walls over the long term.
Product Certification：
Load capacity report / Material analysis report / ETA certification / Seismic test report / 4000-hour salt spray test report / CE certification
Scope of application：
Suitable for dry-hung anchoring of stone, ceramic, sintered stone and fibre cement panel façades.
Product Advantages
Anti-loosening, secure anchoring
A patented anti-loosening and anti-back-out structure grips the back of the panel without slipping, solving the industry-wide problem of back bolts working loose under sustained vibration. Dry hanging is safer as a result.
Low-stress installation, minimal panel damage
Electric drive-in installation creates no expansion pressure, so stress concentration around the hole is small. This greatly reduces the risk of chipping and cracking in brittle panels such as stone and sintered stone, improving yield.
Seismic and weather resistant, stable long term
Suits alternating loads from wind vibration and earthquakes. The anti-loosening structure resists fatigue, and the anchor is corrosion and ageing resistant — reassuring for high-rise and coastal curtain walls.
