Great quality. Lot's of mounting options. - I haven't been able to find a suitable phone mount for my truck. There's lots of cheap plasticky crap out there with varying bad reviews. I found a metal one that's highly rated and seemed simple and solid. But it has the 1" ball for a RAM mount. I've got RAM mounts for a few items on my motorcycles and the airplane, so I shopped around and found this base. The diameter of the base is 2.5". As it turns out, the (useless) coin holder in my Toyota Tundra is located exactly where I wanted a phone holder and the round hole it was mounted in is 2.5". Boom! I'm actually really happy with how this turned out. Rock solid, and no more phone sliding around the console. Review: Right Item for the Right Purpose - For those of you that are looking at this single side view of a RAM Mount and wonder what is meant by "swivel base", I am here to clear this up once and for all, because I took the risk and ordered it. When delivered, the item was in three pieces (i.e. the wing nut to adjust, the square mounting plate, and the RAM ball receptacle). The bottom plate has a molded circular disk mounted on a square pedestal. So, your ball receiver bottom goes over this circle and can grip the square/multi sided pedestal when you tighten the wing nut. Simultaneously, the 1" ball you inserted will also be gripped and tightened. Once full tight, the bottom will NOT swivel as it is secured on straight edges but once you loosen the wing nut, you can swivel the bottom near the plate and of course your ball can move around too. So, fear not if you needed a short stubby base rather than a base and an arm that would cause your device to suddenly collapse mid air. My use case was to use this mount on a Seadoo Water Ski to hold a Garmin GPS/Fishfinder (model 43cv or 4" screen). When my Seadoo slams down after launching over a wave, a longer arm would immediately collapse or bend under the strain. This short one is only a single point of failure, rather than two points. So, it is a no brainer for my specific use case. I hope this helps. =) ## Features - Swiveling single socket arm allows for 360-degree rotation on 2.5" round base featuring the industry-standard AMPS hole pattern - Compatible with B size RAM ball components - Made of high-strength composites for durability and reliability in the most demanding environments ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00AH5U2QA | | Additional Features | Overall Height: 2.42" | | Best Sellers Rank | #18,704 in Cell Phones & Accessories ( See Top 100 in Cell Phones & Accessories ) #417 in Computer Monitor Accessories #798 in Cell Phone Automobile Cradles | | Brand | RAM MOUNTS | | Color | Black | | Compatible Devices | Cameras | | Compatible Phone Models | 1 | | Compatible with Vehicle Type | Automobile | | Customer Reviews | 4.7 4.7 out of 5 stars (603) | | Enclosure Material | High strength composite | | Global Trade Identification Number | 00793442927508 | | Item Dimensions | 1 x 1 x 1 inches | | Item Weight | 3.2 ounces | | Manufacturer | RAM Mounts | | Mfr Part Number | RAP-B-200-1-293U | | Model Name | RAP-B-200-1-293U | | Model Number | RAP-B-200-1-293U | | Mounting Type | swivel | | Shape | Arm, Round | | UPC | 066511969816 018627585046 793442927508 | | Warranty Description | See RAM Mounts manufacturer warranty for details | | Water Resistance Level | Not Water Resistant | | Weight Capacity Maximum | 2 Pounds | ## Product Details - **Brand:** RAM MOUNTS - **Color:** Black - **Compatible Devices:** Cameras - **Compatible Phone Models:** 1 - **Mounting Type:** swivel ## Images ![Single Socket Arm with Swivel Round AMPS Base, B Size 1" Ball Mount with 360° Rotation for RAM Device Holders RAP-B-200-1-293U - Image 1](https://m.media-amazon.com/images/I/41hdluSlr6L.jpg) ## Available Options This product comes in different **Customer Package Type** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's a RAM.
