RAM X-Grip Universal Cradle for 12" Tablets with Dual Suction Cup Base

RAM-B-189-UN11U – RAM® Universal X-Grip® Holder for 12" Tablets with Dual Suction Cup Mount

The RAM-B-189-UN11U pairs the RAM® X-Grip® cradle for 12" tablets with a dual Twist-Lock™ suction cup base and a medium double socket arm, giving a strong, tool-free hold on glass and non-porous flat plastic surfaces.

Key Features

• Spring-loaded 'X' design with rubber caps grips tablets securely without hiding the screen; fits most 12" tablets
• Easy-access grip knobs on the back of the holder allow quick release of the tablet
• Dual twist-lock suction cups provide a secure base on smooth flat surfaces
• Medium double socket arm adjusts to almost any angle on RAM's ball-and-socket design
• Powder-coated marine-grade aluminium, powder-coated steel components and high-strength composite for durability in demanding environments
• Lifetime warranty on the mount hardware, with the suction cups excluded as a wear item

Works With

Most 12" tablets with or without a sleeve, as well as some smaller tablets. The X-Grip® cradle is a composite spring-loaded design with expandable grip arms and an additional bottom support keeper. Both cups sit on a single fixed plate, so this kit suits flat or gently curved glass; for a strongly or compound curved screen see the pivot version, the RAM-B-189-PIV1-UN11U. Always check the dimensions of your device with its case, sleeve or skin fitted against the figures below.

Compatible Devices

This kit uses the same RAM-HOL-UN11U X-Grip® cradle — see the full compatible device list on the RAM-HOL-UN11U listing.

What's Included

• RAM-B-189BU dual twist-lock suction cup base
• RAM-B-202U round base with 1" ball (x2)
• RAM-B-201U medium double socket arm
• RAM-HOL-UN11U X-Grip® spring-loaded cradle

Care & Warranty

• Smooth, non-porous surfaces only — anything rough or textured lets air past the seal and the cups will not hold.
• Clean the surface thoroughly before you apply the cups.
• If the vehicle is left sitting in extreme heat or cold, release the cups and stow the mount rather than leaving it loaded.
• RAM® classes suction cups as a general wear item, so the cups are excluded from warranty cover. The base, arm and cradle hardware are covered as normal.

FAQs

Is this a complete mount? Yes. The dual suction base, round bases, medium arm and X-Grip cradle are all included — there's nothing else to buy to get your tablet onto the glass.

Will it hold on a curved windscreen? Both cups sit on a fixed plate, so this kit is at its best on flat or gently curved glass. On a strongly or compound curved screen the pivot version, the RAM-B-189-PIV1-UN11U, is the better choice — each of its cups articulates independently and can be repositioned to suit convex or concave surfaces.

Will my tablet fit with a case on? Measure the width of your tablet with the case, sleeve or skin fitted. The cradle opens from 184.2mm to 222.3mm wide and takes devices up to 22.2mm thick.

Are the suction cups covered by the warranty? No. RAM® treat suction cups as a general wear item, so they sit outside the lifetime warranty. The rest of the mount hardware is covered as normal.

What surfaces will the cups stick to? Glass and other smooth, non-porous surfaces. Textured dashboards, matte plastic and anything with a grain won't hold. Clean both the cup face and the surface before mounting — a RAM adhesive disk is the usual workaround where there's no suitable glass.

Is a 12" tablet too heavy for suction? The dual-cup base is specified to 907g in standard use, which covers most 12" tablets. In high-vibration use — off-road, marine, or a work vehicle on rough ground — a drilled or clamped base will always be more secure than any suction mount.
