Metallics MBS10160 Anchor 10 x 160mm Nylon Frame Plug w/ (50 pcs)

The MBS10160 is a 10 x 160mm nylon frame plug, so it takes a 10mm hole and gives 160mm of embedment length. It comes 50 pieces to the pack, which is the quantity to plan around when you are estimating a run of conduit strap or box mounting points.

That is exactly what the long body is for. A 160mm frame plug passes through the fixture and any standoff layer, then expands in the base material at the far end, so it suits fixing through window and door frames, battens, or insulation into brick, block, or concrete. What matters is that the last part of the plug lands in solid base material, not in the soft layer, so measure your total standoff and confirm the plug still reaches sound substrate.

The pack is described as 50 nylon frame plugs. Treat the screws as a separate line unless your pack is labelled as a complete plug-and-screw assembly, and match the screw diameter and length to the 10 x 160mm plug so it drives the full body.

For light to medium loads on masonry it is a common choice: the nylon body expands against the hole wall as the screw drives, and nylon will not corrode the way an untreated steel anchor can. Use it for boxes, straps, and raceway supports. For heavy or vibrating loads, or anything overhead carrying real weight, a mechanical steel anchor is the better call. The MBS10160 sits in the Metallics anchor line for electrical work.

Add up the thickness of what you are fastening, plus any shim, insulation, or furring behind it, then add the embedment you need in the base material. If that total is close to 160mm, the MBS10160 is the size; if you are fastening straight to bare masonry with nothing in between, a shorter plug is the cheaper and easier fix and a 160mm body just leaves you drilling deeper than you have to.
