Yes4All Cast Iron Weight Plates, 1-Inch

A set of mismatched weights or plates that do not fit your bar can make home strength training harder to organise. These Yes4All cast iron weight plates have a 1-inch centre hole for standard bars and dumbbell handles, giving you a straightforward way to add resistance to familiar exercises without switching to a different bar format.

They’re offered as singles, pairs and sets of four, so you can choose a quantity that suits your setup.

Where it shines

Cast iron makes sense if you want weight plates for regular lifting rather than a lighter, less substantial material. The plates have a semi-gloss black paint coating, which the product description says helps protect against rust and corrosion. That’s useful for equipment stored between workouts, though a painted finish should not be treated as a guarantee against rust in every storage environment.

The 1-inch opening is the key fit detail. These plates are intended for standard 1-inch bars and dumbbell handles, and the listed exercises include biceps curls, triceps extensions, chest flies and shoulder presses. For example, you could load a suitable dumbbell handle for curls, then move the plate to a compatible bar for presses. If you prioritize a familiar, simple plate format, this is a practical approach, if you prefer a different sleeve size or a different style of equipment, the fit may rule it out.

What to know

The product name advertises a 5–40 lb range, while the detailed description lists options of 5, 7.5, 10, 15, 20 and 25 lb. The exact weight depends on the option selected, so the advertised range and the listed choices are worth keeping in mind when choosing. Singles, pairs and sets of four are also offered, the description does not specify which weights are grouped in each set.

There are no stated plate dimensions or handling features beyond the centre-hole size and a design described as easy to move, load and store. Given its design, this is a conventional cast iron plate, not a soft or compact alternative for someone who wants equipment that can be stored in very little space. A bar or handle with a different sleeve diameter won’t suit the 1-inch opening.

Best use cases

These plates are aimed at strength training and toning with standard bars or dumbbell handles. They can suit a home routine built around the listed movements, especially if you want to add or change resistance without buying a different type of plate. The choice of singles, pairs or sets of four also gives some flexibility in how many plates you bring into your setup.

It suits you if your equipment uses a 1-inch fit and you want cast iron plates for familiar lifting exercises. It isn’t for you if your bar or handle has a different diameter, or if you need exact set contents and dimensions before deciding, those details are not provided here.

Bottom line

Choose these if the 1-inch centre hole matches your equipment and cast iron is the format you want for home strength work. The main trade-off is limited detail about dimensions and set contents, alongside the difference between the stated 5–40 lb range and the weights listed in the description. If those specifics matter to your setup, this listing leaves questions unanswered, if fit and a standard plate format are your priorities, it covers the essentials.
