Plastic Door Shim Cards 0.5 mm (5 pcs)

Plastic door shim cards, 0.5 mm

Locked out because a door closed behind you? With these door shim cards you can open a door that has closed on its spring latch, without forcing the lock and without damage. This technique is called latch shimming; in the Netherlands the cards are known as flipperkaarten. They are used by locksmiths, facility managers and DIY enthusiasts.

Why these shim cards?

• 0.5 mm thick – stiffer than standard shim cards, for more strength and a longer life.
• Set of 5 – always a spare to hand.
• Flexible – slides easily into the gap between the door and the frame.
• Reusable and wear-resistant.

How latch shimming works

The latch is the angled bolt that clicks into the frame when the door closes. You slide the card into the gap between the door and the frame – not into the keyhole – at the height of the latch, usually at a slight angle. The card presses on the angled side of the latch and pushes it back into the door. On a stiff door you can use two cards together for extra strength.

What it does not open

A shim card will not open a door that has been locked with the key (a thrown deadbolt). It also does not work on latches with an anti-shim plunger (a deadlatch) or behind a latch guard plate.
