I Bought A Below-the-oven Kitchen Drawer But The Fitting Is Difficult As The Dra

r has 2,hollow,sides which require a metal fitting to be screwed onto the back of the drawer front, and that is then slotted into the hollow front of the side piece. It is then screwed up,in,the hollow side. Unfortunately I put the both fittings into the hollow sides first,not realising there were magnetic devices in the sides which prevented me withdrawing the fittings so I could screw them onto thedrawer front back first. can i safely rip out the fittings from the hollow sides, so I can screw them onto the drawer front backs, withut damaging them? d roberts
