Kent Pro-Scraper 12in
KENT Marine ProScraper's are ideal for cleaning scratched glass or acrylic. With rubberized handles and blade attachments from strong ABS plastic and stainless steel these units will not rust and resist breaking. The plastic blade will gently scrape off most naturally-occurring algae without scratching the glass or acrylic surface and steel blades will work on that hard coralline algae and calcifed deposits.
ProScraper II metal and plastic blades are interchangeable and replaceable.
