What to know before buying
Listing details to confirm
Listing details are inconsistent or unconfirmed: the main details give material as Chrome, while the product specification says Zinc Alloy and another description says aluminum alloy. The listed weight of 25 Grams conflicts with the A+ specification of Approx. 1288g / 45.4oz, and the overall dimensions differ in scope from the separate panel measurements. Confirm the exact material, weight and dimensions for the selected listing before purchase. The listing's broad gate and door compatibility claims do not confirm fit for a particular door or glass installation.
