The 18-inch Big Ben cage frame doubles your roll-out speed on big walls. Where it earns its $20, where the cage design and 18-inch-only sizing bite.

Verdict: ★ 4.3 / 5
The Big Ben is the 18-inch frame I reach for first when a job is mostly long, open wall. It rolls fast, the polypropylene body shrugs off solvent and dried paint, and the replaceable legs mean a $20 frame survives years instead of one season. It wins on speed and durability for the money. It falls short on versatility, because it’s 18-inch only and uses a friction-fit cage instead of a spring-lock cover system.
Buy it if you regularly roll big walls, ceilings, or siding and you’re tired of doubling your passes with a 9-inch.
Skip this if your typical job is one bedroom at a time. A wide frame on a small room is more weight than benefit.
What Is the Wooster Big Ben Roller Frame?
Wooster Brush has been making painting tools in Wooster, Ohio since 1851, and the brand sits where Purdy sits for most US pros: the default you grab without thinking about it. Wooster’s roller lineup runs from the consumer Shergrip up through the contractor Sherlock cage and the wide-format frames built for production crews. The Big Ben lives in that last group.
The Big Ben (model BR045) is an 18-inch cage frame. The pitch is simple math. An 18-inch cover lays down roughly twice the width of a standard 9-inch in a single pull, so on a wall with long open runs you finish in about half the passes. The frame body is molded polypropylene, the legs that hold the cage are fiberglass-reinforced nylon, and the handle is threaded for Sherlock GT and standard extension poles. It isn’t a fancy tool. It’s a fast one.
Which Wooster Wide Frame Are You Buying?
Wooster sells more than one big frame, and the names blur together at the rack. This review covers the cage-style Big Ben. If you’re standing in the store, here’s how to tell them apart.
| Frame | What it is | Read instead |
|---|---|---|
| Big Ben (BR045), 18-inch (this review) | Plastic cage frame, friction-fit covers, replaceable legs | — |
| Wide Boy (RR302), 18-inch | Plastic frame with a built-in handle grip, lighter-duty | Wide Boy note in the frames round-up |
| Sherlock Wide Boy “Hulk”, 18-inch | Heavy-duty wide frame with the Sherlock end-cap | Separate Sherlock frame review |
| Sherlock GT (9-inch) | Standard-width spring-lock frame, the everyday workhorse | Our roller frames round-up |
If you wanted a 9-inch frame for one-room jobs, the Big Ben is the wrong tool. It only comes in 18-inch. The whole point is width.

Per-Attribute Sub-Scores
| Attribute | Score | Why |
|---|---|---|
| Speed / coverage | 9/10 | The reason it exists. Roughly half the wall passes of a 9-inch on open runs. |
| Build quality | 9/10 | Polypropylene body and reinforced legs hold up to years of paint and cleanup abuse. |
| Cover swaps | 6/10 | Friction-fit cage. A swollen or low-bore cover fights you going on and coming off. |
| Versatility | 5/10 | 18-inch only. Useless on small rooms and tight cut-in-heavy work. |
| Value | 9/10 | Around $20, and the replaceable legs stretch its life well past one job. |
What It’s Good At
- Raw speed on open wall. This is the whole case for the frame. On a great-room wall or a stairwell with twelve feet of clear run, I lay down a coat in about half the strokes a 9-inch needs. Less stop-start, fewer lap lines, a faster job. On exterior lap siding the gain is even bigger because the runs are longer.
- A body that takes abuse. The polypropylene frame doesn’t corrode the way a bare-wire budget cage does, and dried paint chips off it instead of welding to it. I’ve left one caked overnight, soaked it the next morning, and had it back in service. The plastic doesn’t care about lacquer thinner or denatured alcohol during cleanup.
- Replaceable legs. This is the quiet feature that earns the rating. The fiberglass-reinforced nylon legs (part R085) pop out and swap when one finally cracks. A $20 frame that you repair instead of replace is rare in the wide-format aisle, where most frames are throwaways.
- Pole compatibility you already own. The threaded insert takes standard and Sherlock GT poles, so the frame drops onto the extension setup most painters already keep in the van. No proprietary pole to buy.
Where It Falls Short
- The cage cover swap. This is the real weakness. The Big Ben is a friction-fit cage, not a spring-lock Sherlock design. A fresh, true-bore 18-inch cover slides on fine. A cover that’s swollen from soaking, or one with a slightly tight core, turns into a paint-slick wrestling match mid-job, and getting a loaded cover off without slinging paint takes a rag and patience. If fast cover changes matter to you, the Sherlock end-cap frames are worth the step up.
- It flexes under a heavy load. Eighteen inches of thick-nap cover full of paint is a lot of mass hanging off a plastic cage. On a flimsy telescoping pole the frame will chatter and skip, and you’ll see it in the finish. The fix is a stiff pole, but that means the frame demands gear you might not own. Pair it with a rigid fiberglass production pole or the speed advantage evaporates into stipple.
- 18-inch only, so it’s a specialty buy. There’s no 9-inch or 14-inch Big Ben. On a normal one-bedroom repaint the width is dead weight, awkward in corners, and overkill on short walls. This frame is for jobs that are mostly big flat surface. Buy it as a second frame, not your only one.
Who It’s for / Not For
Buy this if you’re repainting whole-house interiors, great rooms, ceilings, or exterior siding, and you keep a stiff extension pole on hand. The speed gain on open wall pays for the frame in saved hours on the first big job.
Skip this if your work is room-at-a-time interiors, heavy on cut-ins and small walls, or you don’t want to invest in a rigid pole to feed it. For that work, a 9-inch Sherlock frame gives you more control and less fuss. See the full roller frames round-up for the everyday-width pick.
Honest Alternatives
Cheaper: Wooster Wide Boy 18-inch (RR302), ~$12–18
The Wide Boy is the lighter wide frame with a molded grip built in, so you can run it off the frame alone for low ceilings without threading a pole. It’s a notch less rigid than the Big Ben and the grip isn’t as comfortable on long days, but it’s the cheaper way into 18-inch rolling. The right call if you want width once in a while and don’t want to spend $20. → Amazon
Pricier upgrade: Wooster Sherlock Wide Boy “Hulk” 18-inch, ~$30–45
Heavier-duty wide frame with the Sherlock end-cap, so covers seat and release with a spring-lock instead of friction. Stiffer cage under a loaded cover, smoother cover swaps, built for crews running it all day. Costs roughly double the Big Ben. The right call for production painters who change covers constantly and want zero flex. → Amazon
Specialty: Wooster Sherlock GT 9-inch frame, ~$10–14
Not a competitor so much as the other tool you should also own. The 9-inch Sherlock is the control frame for cut-ins, small rooms, trim-adjacent rolling, and touch-ups, where 18 inches is unusable. Most painters carry both and pick by the wall in front of them. → Amazon
Where to Buy
| Retailer | Notes | Buy |
|---|---|---|
| Home Depot | Stocks the 18-inch (model 0BR0450180); easy single-unit pickup | → Home Depot |
| Lowe’s | Carries the genuine BR045-18 frame | → Lowe’s |
| Amazon | Sold solo and in multi-packs; check per-unit price on bundles | → Amazon |
| Sherwin-Williams | Pro paint stores carry it alongside 18-inch covers | → SW stores |
| Woosterbrush.com | Product specs and dealer locator | → Wooster |
A single frame runs about $20 at the big boxes. The multi-packs on Amazon only make sense for a crew running several at once; a homeowner needs exactly one. Buy the R085 replacement legs at the same time if you’re hard on gear, and the frame becomes a multi-year tool instead of a disposable.
FAQ
Is the Big Ben frame worth it over a standard 9-inch roller? Only on big open surfaces. On a single bedroom or a cut-in-heavy hallway, a 9-inch gives you better control and the speed loss is small. On a whole-house repaint, a great room, or exterior siding, the 18-inch width roughly halves your wall passes. It’s a specialty tool to own alongside a 9-inch, not a replacement for it.
Does the Big Ben use Sherlock spring-clip covers or slide-on covers? Slide-on. It’s a cage frame, so any standard 18-inch cover slides over the metal cage and friction holds it. There’s no Sherlock spring-lock end-cap. The downside is that a swollen or tight-bore cover can be a slick wrestle to seat and remove during a job.
What extension pole works with it? The threaded insert fits Sherlock GT and standard threaded poles. Use a stiff one. A loaded 18-inch cover is heavy, and a flimsy telescoping pole will flex and chatter, which shows up as stipple in the finish. A rigid fiberglass or aluminum production pole is the right pairing.
Are the legs really replaceable? Yes. The fiberglass-reinforced nylon legs are Wooster part R085, and they swap out if one cracks. That turns a $20 frame into something you repair instead of toss, which is rare at this price.
