Decor Grates AC410-BLK Victorian Floor Register, 4 x 10, Cast Iron Black, 2 Sq Ft
  • Victorian Scroll Design Cast Iron Black floor register
  • The edges have been squared off, so it can be installed as a drop in register or a flush mount register. If used as a drop in register, it’s easy to install and no tools required. If used as a flush mount register, you need to cut your flooring, so that the opening in your flooring material is the same size as the register face plate. Depending on the thickness of your flooring, you may need to add shims underneath the register to make it flush with the flooring material.
  • Metal damper boxes rust and seize up, so we make our damper boxes with recycled high impact polystyrene; this is not a cheaper option, it’s the best option
  • Solid Cast Iron face plate - won't chip or fade
  • Filter retainer and filter are sold separately

Durability

It is often the case in home improvement projects that you have to sacrifice durability to get the perfect aesthetic. Not so with cast iron floor grates!
The heavy-duty cast iron construction can literally take anything you can throw at it. Go ahead and walk on your new cast iron vent cover. You won’t even see a hint of warping or bending as is common among floor registers made from cheaper metals.

Affordability

Don’t let that last sentence scare you. It’s true that cast iron floor grates are more expensive than cheaply-made vent covers. However, you get incredible value.
All in all, it’s actually an inexpensive way to add the cherry on top of your vintage decorating. Because of their durability, you won’t be replacing your cast iron register covers anytime soon. When you buy the cheapy ones, you have to factor in how many times you have to rebuy them because they get dinged and bent so easily.

Ease of Use

Installing a cast iron floor register is a no-brainer. The hardest part is getting the right measurements. Always measure the opening of the duct rather than the old register and be aware when buying them that there are typically two sizes — boot size and register size.

The boot size is the size of the hole in the floor that the cast iron register will fit into. The register size is the finished outside size of the register.
