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.
