Harken 45mm Triple Element Block w/Swivel

45mm Triple Element Block with Swivel. Element blocks introduce sideplates that combine forged aluminum and compound curves for strength. They are simultaneously contemporary and very robust. Element’s design pairs the minimum amount of metal required to protect the sheave with a proven journal bearing. So size for size, Element is priced significantly lower, than our previously least expensive blocks.. Sideplates are hardcoat-anodized to resist corrosion. A tough composite bearing sheave resists corrosion for a long service life.Specifications: Sheave: 45mm / 1-3/4in, Length: 108mm / 4-1/4in, Weight: 265g / 9.3oz, Shackle pin: 6mm / 1/4in, Maximum line: 12mm / 1/2in, Maximum working load: 1050kg / 2315lb, Breaking load: 2100kg / 4630lb.
