The CANVAS Extra-Large phone clamp is made to maximize compatibility with the largest smart phones available, and with many thick phone cases!  

This spring loaded clamp expands to a max of 4.3" - which gives you over an additional inch of expansion compared to our standard phone clamp.  Both sides of the phone clamp expand, offering additional reach and flexibility. 

Compatible with all CANVAS Lamp Models, using the same mounting screw and spacer included with your CANVAS Lamp purchase. 

*Phone shown in product photos is an iPhone 14 Pro Max with an Otterbox Defender phone case - total width: ~3.5"
