Does anyone have a trick of the trade for removing a breaker panel that has been secured to the concrete wall with a hammer type nail in fastener, such as a Ramset Surelock. The basement waterproofing guys are going to patch a rod hole behind the service panel, so I have to remove the panel and then put it back up when they are done. I don't want to disfigure the panel.
Thanks

Normally I'd use a large bar, but considering you want to reuse it you may be able to drill the heads of the pins off (start with a very small bit). Hopefully the drill bit is harder than the pin-head. In the future you might consider fastening the panel by another method.

We usually use an angle grinder, to grind the head off the fastener, it works good, doesn"t damage the panel.

Drilling works for me, I have also ground them off. In real tight spots I have used a dremel tool to grind the head off. Rod

Thanks everyone, I appreciate your advice. Personally I have never used these hammer fasteners for mounting panels. I usually use plastic anchors with #10 x 1" hex head sheet metal screw. They secure the panel rigidly, and they enable you to remove the box or panel if you need to.

You can also reshoot over the existing head without a new fastner loaded in the gun.

It disorts the panel a little, yet can be beaten back into shape, then a little caulk to seal back up if necessary.

Try tapping the head of the existing fastener with a drift pin....I don't know about concrete, but this often causes cement block to break free of the fastener, allowing it to be easily pulled free.
