Additional Information
Short backset for aluminium. 28mm backset latches are commonly needed for aluminium framing systems where a standard 60mm backset will not fit.
Order the correct hand. The left-hand and right-hand latches are separate parts, not one reversible latch - check your door handing before ordering.
Two handed parts on one listing. This listing covers both handed latches - the left-hand BLS275000LH and the right-hand BLS275000RH. Tell us which hand you need when you order.
