Push Points install without the use of special tools, making them a favorite of glaziers and DIY'ers. Just push them carefully into place with a putty knife, chisel or slotted screwdriver. Use Push Points for wood sash glazing, green houses, picture frames, mirror frames, and more. They are zinc coated to resist corrosion. The benefit being that it avoids the use of hammer and nails to pin glass into a frame, which can be risky.
