Four window lock parts here are listed as fitting hardware known as Clearview: a glass panel lock plunger, a keyed window catch and spring, and two non-keyed window catches and springs. Clearview is not a single source — several unrelated Australian businesses trade under the name — so treat it as a fitment note rather than a maker, and match on the part instead of the label. The same catches are listed against Bradnam’s® and Wideline® springs, and the plunger against Dayview™ and others, which tells you these are common patterns rather than anything proprietary. Because the name will not identify the part for you, take the old catch out and compare the body, the spring, the fixing centres and whether it is keyed. If the lock came from a glass sliding panel rather than a sash window, the plunger is the one to compare.
