A suction cup flag holder should match the way you display the flag. A garden flag hanging flat against a window, three small flags on a parked RV, and a visibility flag on an off-road vehicle need different hardware. Start with the mounting surface, the flag’s attachment, and the maker’s limits for the exact holder.
For a parked RV or stationary display with small flag staffs, Camco 45506 is the most clearly specified option here. For a sleeve-style garden flag on window glass, look at Evergreen 23011A. For specialized off-road or skier-down use, SeaSucker offers purpose-built mounts with different fit requirements. A no-drill mounting method alone does not establish that a holder is suitable while driving or boating.
Choose the holder for your application
| Display | Model to consider | Fit to check | Main limitation |
|---|---|---|---|
| Small flags on a parked RV or stationary smooth surface | Camco 45506 suction cup triple holder | Up to three staffs, each no larger than 3/8 inch | Camco says to remove it before traveling |
| Decorative garden flag on a window | Evergreen 23011A window hanger | Garden-size flag and its sleeve; window glass | No published pole-load or traveling-use specification on the product page |
| Off-road visibility flag | SeaSucker SM6310 Visibility Flag Mount | 1/4- to 1/2-inch pole; smooth, nonporous surface | Flag and whip are separate; no universal road-speed rating established here |
| Skier-down flag on a boat | SeaSucker MB6311 Skier Down Flag Holder | 1/4- to 1/2-inch pole; flag no larger than 20 × 20 inches | Flag and pole are separate; verify the installation for your boat |
Camco 45506: a straightforward choice for stationary small flags
The Camco 45506 is a black ABS plastic holder with three staff openings. Camco specifies a 3 × 5-inch holder and flag staffs up to 3/8 inch. Its instructions call for moistened cups on a clean, smooth, nonporous surface and removal before travel.
That makes it a practical starting point for a parked campsite display if your flags fit those openings. It is a holder rather than a full flag-and-pole kit. Do not substitute model 45505 by accident: Camco identifies that version as a screw-mount holder.
Camco publishes a three-pound figure for each suction cup. Do not turn that number into an allowable flag size, a wind limit, or permission to leave the display attached on the road. Those are different questions from whether the cup can hold a static load.

Evergreen 23011A: for a garden flag on window glass
The Evergreen Garden Flag Suction Cup Window Hanger, SKU 23011A is a window-display accessory. Evergreen describes suction cups that attach to glass, a weather-resistant metal-and-plastic construction, and suitability for indoor or outdoor garden-flag display.
Choose this style when the flag hangs from a sleeve across the top. Measure that sleeve and confirm that it can slide onto the hanger and hang without bunching. The manufacturer says it fits garden-size flags, but its page does not give a maximum flag width, a staff diameter, or a load rating. Avoid assuming that a similarly named 15-inch hanger or another Evergreen part has identical dimensions.
This is the relevant category for seasonal decorations on a house window. A statement that a product is suitable outdoors does not establish suitability on a moving car or boat. If you need the flag to project away from the glass on a long pole, choose a holder documented for that arrangement.
SeaSucker SM6310: a purpose-built off-road visibility mount
The SeaSucker SM6310 Visibility Flag Mount is designed for off-road visibility flags. Its holder accepts poles from 1/4 to 1/2 inch and adjusts to five positions: 0, 30, 45, 60, and 90 degrees. The flag and whip are not included.
SeaSucker specifies smooth, nonporous mounting surfaces and explicitly excludes rough, textured spray-on vehicle coatings such as LINE-X. The 4.5-inch vacuum mount has an orange indicator band that shows a loss of holding power. Make sure your intended location leaves that indicator accessible for inspection.
The published 120-pound figure is a vacuum-mount pull rating. It is not a 120-pound flag allowance or a guaranteed wind or driving-speed limit. Before using a particular whip and flag while moving, confirm the complete setup and operating limits with SeaSucker. Pole diameter alone does not answer every installation question.
SeaSucker MB6311: a distinct option for a skier-down flag
The SeaSucker MB6311 Skier Down Flag Holder accepts a 1/4- to 1/2-inch pole or whip and is specified for flags up to 20 × 20 inches. It uses a 4.5-inch vacuum mount. Neither the flag nor the pole comes with the holder.
That package distinction matters: a photograph with an orange flag does not mean you are buying the flag, pole, and holder together. Choose a flag and pole within the stated dimensions, then confirm the mounting location and installation with the manufacturer for your boat. Do not transfer specifications from the off-road mount merely because both use a vacuum base.
A holder also does not establish that a flag satisfies the requirements where you boat. Check the relevant boating authority’s current rules for the flag’s size, color, visibility, and when it must be displayed.
What to measure before you order
- The part that enters the holder. Measure the staff’s outside diameter where it sits in the socket, including any ferrule or thicker section. For a hanging garden flag, measure the sleeve instead.
- The actual mounting area. Identify glass, painted metal, fiberglass, or another finish. Check that exact surface against the chosen maker’s instructions; “fits an RV” is not a specification for every RV panel.
- The whole flag assembly. Record the flag dimensions, pole length, and attachment style. Ask the maker about any limit missing from its documentation before using a longer pole or larger flag.
- What comes in the package. A holder, a replacement suction cup, and a complete flag kit are different purchases. Confirm the model number and included pieces at checkout.
- Whether the display will move. Parked campsite decoration and use underway are separate applications. If a manufacturer tells you to remove a holder before travel, plan storage for it before you depart.
Installation and maintenance depend on the mount
Use the instructions supplied with the exact product. Camco’s moistening instruction is specific to its suction cups; it is not a reason to apply the same procedure to every vacuum mount or adhesive-backed accessory.
For SeaSucker products, the manufacturer’s maintenance guidance calls for clean mounting surfaces and a clean sealing edge. Inspect the pad for cuts or nicks, which require replacement. SeaSucker says there is no fixed holding duration: the surface, mount condition, load, and other factors affect it. Re-pump when the orange indicator band appears, following the product instructions.
If you cannot maintain the required seal on the specified surface, stop using that installation and resolve the cause. A larger flag, extra suction cup, improvised strap, or stronger-sounding lifting rating is not a substitute for a documented mounting arrangement.
Frequently asked questions
Can I drive with a suction cup flag holder attached?
Only choose an arrangement explicitly intended for your moving-vehicle application. Camco 45506 must be removed before traveling. A dedicated off-road mount has a different purpose, but its product name still does not establish a universal highway-speed or wind limit.
Will a suction cup holder stick to textured siding?
Do not assume it will. Camco specifies smooth, clean, nonporous surfaces. SeaSucker SM6310 also requires a smooth, nonporous surface and excludes rough spray-on vehicle coatings. Ask the chosen maker about your exact finish.
Can a window garden flag hanger hold a full-size house flag?
Do not substitute one without a matching specification. A garden-flag sleeve, a small hand-flag staff, and a house-flag pole use different support arrangements. Select by the holder’s documented fit rather than the flag’s appearance in a photo.
Does a suction cup’s weight rating tell me how much wind it can handle?
No. A published holding or pull figure does not by itself specify a flag’s permitted dimensions, pole length, or operating wind conditions. Use the complete product’s instructions and ask its manufacturer when the relevant limit is missing.
Are Camco 45505 and 45506 the same holder?
No. The Camco catalog identifies 45505 as the screw-mount version and 45506 as the suction-cup version. Match the part number before buying.
