If you have an old standard barbell or a pair of spin-lock dumbbell handles and want to add weight in small steps, 1-inch plates like these are the simplest fix. You don't need to replace anything. You just add a little more.
Check the 5 lb plate listing on Amazon
One thing up front: this is not a discount. The Amazon listing is at its regular price of $28.99, with no sale price. We're covering it because it's a useful, no-frills product for a specific kind of setup, and only if the hole size matches yours.
Check your bar first: 1-inch hole, standard bars only
This is the whole decision. These plates have a 1-inch hole, which fits standard bars and dumbbell handles. They are generally not compatible with Olympic bars, or with handles that have roughly 1.15-inch openings.
Before you click anything, measure the sleeve or handle where the plates would sit. If it's 1 inch, keep reading. If it's an Olympic bar (2-inch sleeves), these won't work, and no amount of wishful thinking will change that.
What you get for $28.99 (and why you should confirm the quantity)
The listing title describes the WF Athletic Supply Cast Iron 1-Inch Standard Grip Plate as a set of 2 plates at 5 lb each, 10 lb total, in gray.
Here's the catch. WF Athletic Supply's own product page says its grip plates are sold individually. That doesn't match a "set of 2" title, so we can't tell you for certain that the listing ships as a pair. Before you check out, confirm the selected option (5 lb) and the quantity on the live listing. Also confirm the seller and brand while you're there.
What the listing and the manufacturer page describe:
- Solid cast iron with an enamel coating
- Machined 1-inch hole
- Three-hole grip design for carrying and loading
- 5 lb per plate, gray finish
- Manufacturer sizes: 2.5, 5, 10, and 25 lb
If you want even smaller jumps, the 2.5 lb size exists. If 5 lb is too small for what you're doing, the larger sizes are there too.
Where small plates make sense: curls, presses, warm-ups, and endurance circuits
Five-pound plates are for small increments, not big loads. Typical uses include:
- Small jumps on a standard barbell or dumbbell handle. This is the main reason to buy them.
- Curls and triceps extensions, where a few extra pounds per side matter.
- Chest presses, flyes, and shoulder presses, especially when you're progressing slowly.
- Warm-up sets before heavier work.
- Endurance circuits and general conditioning, where you load and unload plates often.
The three-hole design can also work as handholds for plate-loaded movements. The listing title also makes broader claims about muscle toning and weight loss. Those are marketing language, and we're not repeating them as fact.
What buyers like, and what the 4.7-star rating does and doesn't tell you
An Amazon result for the WF Athletic Supply 1-inch standard grip plate shows a 4.7/5 rating from roughly 1.3K reviews. That points to generally strong customer reception.
There are some caveats:
- The rating may not apply specifically to the 5 lb two-pack. Reviews can cover multiple sizes or options under one listing.
- The result doesn't include a breakdown of complaints, so we can't say what the unhappy reviews are about.
- The manufacturer page and a Strength Product Reviews page both describe the plates favorably, but neither is independent testing. The review page is promotional in tone and includes testimonial-style quotes.
Read the lower-star reviews on the live listing, and look for comments about the specific 5 lb option, the hole size, and the finish.
Noise, floors, and collars: the practical stuff
- Cast iron is rigid and loud. If you drop a plate on a hard floor, expect a bang and possible floor damage. Protective flooring is a good idea.
- Grip holes aren't a safety feature. They help with carrying and loading, but they don't replace collars or other secure hardware. Use proper collars on your bar.
- Inspect on arrival. Cast iron plates can vary slightly in actual weight and finish. Check the machined hole and the coating when they show up, and make sure the plates slide onto your bar.
- No published guarantees. We didn't find a manufacturer-backed weight tolerance, warranty, or drop-use rating, so don't assume one.
Is $28.99 for 10 lb a good price?
We can't give you a verified price-per-pound comparison, because we don't have current verified prices for other sellers, and we don't have price history for this listing. What we can say is that $28.99 is the regular price today, not a markdown.
If this isn't quite the right fit, there are other routes depending on your setup:
- Yes4All makes standard 1-inch plates in single, pair, and larger-set configurations.
- CAP makes Olympic plates if you have a 2-inch bar.
- Rubber or bumper plates make more sense if noise and floor protection matter more than compactness.
- Adjustable dumbbells suit you better if storage space and quick weight changes are the priority.
Check current prices on whichever route fits before you decide.
When to skip these (Olympic bars, heavier lifters, limited storage)
- You have an Olympic bar. The 1-inch hole won't fit. Skip these.
- You lift heavy. Five-pound plates add a small amount of load. For advanced lifters, that may be too little to matter.
- Storage is tight. Loose plates take up space, and adjustable dumbbells may suit a small room better.
- Your floor is vulnerable. Cast iron on thin flooring without protection is asking for trouble.
Bottom line
These are plain, inexpensive cast iron plates for people who already own a 1-inch standard bar or spin-lock handles and want small increments. The rating is strong at 4.7/5 from roughly 1.3K reviews, with the caveats above.
The listing is at its regular $28.99, so there's no urgency. If you want to buy, check the Amazon listing, confirm the 5 lb option and that it includes two plates, verify the seller and brand, and buy only if the hole size matches your bar. If you'd rather wait, keep an eye out for a Kinja Deals mention if a coupon or price cut shows up.
