TL3AMB1420T38L Suction Cup Mount 3 in Dia - Secure Monitor/Accessory

In this review the TL3AMB1420T38L Suction Cup Mount is presented as a simple, dependable option for anyone who needs a temporary yet stable mounting point for light equipment. The bottom line: this suction cup is best for users who need a metal platform with a threaded 1/4'-20 x 3/8' stud and a clear vacuum safety system; its biggest selling point is the combination of a 3 in concave cup and a Red-Line Vacuum Indicator that makes secure attachment easy to confirm.

Key Features

• 3 in concave cup: the cup size and concave shape concentrate suction for a stronger hold on flat, smooth surfaces.
• Threaded stud mounting: the 1/4'-20 x 3/8' threaded stud fits common monitor and accessory mounts without adapters.
• Metal platform: a metal platform provides a sturdy connection point for attached devices and resists flex under load.
• Red-Line Vacuum Indicator: a visible vacuum indicator gives a quick, reliable check that the pad is holding properly.
• Instant release lift tabs: built-in lift tabs and a check valve make removal straightforward and reduce the chance of sudden loss of suction.

Who It's For

This suction cup mount is aimed at hobbyists, technicians, and office workers who need a temporary mounting solution for light devices such as small monitors, cameras, or accessory brackets. Its 15 lb max load capacity and 1/4'-20 mounting make it well suited to lightweight monitors, webcams, and peripheral mounts that require frequent repositioning.

It is not intended for heavy permanent installations or textured surfaces; users who need multi-point heavy duty suspension or guaranteed long-term outdoor mounting should look at bolted or clamp-style mounts instead.
