TRIO Flatmount Heavy Duty Suction Cup Mounts No-drill mounting for smooth surfaces, built for high speed and extreme use. Glass, gel coat, smooth fiberglass, and smooth painted metal. This set of four industrial-grade vacuum cups locks your TRIO mount down hard. Each cup holds 65 lb, for over 260 lb of total holding force. These are real vacuum pump cups, not the lever-style cups you find on glass holders. A built-in indicator band lets you confirm the seal at a glance. M6 female threads bolt the cups straight onto your mount. Stainless steel hardware is included in every set. Works as a replacement set or an upgrade for compatible TRIO mounts. Fully removable, so you can move your setup between vehicles, RVs, and boats whenever you need to. Pump and confirm Press the pump until the colored indicator band disappears. That is your visual proof of a full vacuum seal. No guessing. Curved or angled surface The cups conform to a slight curve of about 1 to 2 degrees. For anything more, pair them with Swivel Leg Adapters so each cup sits flush for full contact. Magnets or suction cups? Rubber Coated Magnets are the pick for magnetic steel roofs. Suction Cups are the pick for smooth, non-porous surfaces where magnets cannot grip. Both are removable and need no drilling. Specs Set of 4 Holding force: 65 lb each, over 260 lb total Dimensions: 4.5" diameter x 2" high M6 female threads Stainless steel hardware included
