Screwing a bracket into a glass desktop isn't an option -- these clamp-on trays are built for that
Glass desktops need a clamp-mount tray with padded, adjustable clamps rated for the right thickness. Some clamp trays are explicitly not rated for glass or beveled edges -- these are.
See the glass-safe picksQuick answer: Our top pick for cable management trays for glass desks and other no-drill clamp-mount surfaces is the Mount-It! Clamp-On Under Desk Cable Management Tray, 23.6" (MI-7286BLK) (Best for Glass Desks). If you're looking for best adjustable length, the StarTech.com Under Desk Cable Management Tray (CALW-DESK-CABLE-TRAY) is a strong alternative.
Most cable trays, including the no-drill options in our main comparison, are designed around wood or laminate desktops. Glass desks change the calculus twice over: screw-mounted brackets are off the table entirely, and even some clamp-on trays explicitly warn they're not rated for glass, beveled edges, or uneven surfaces because the clamp can slip or crack the edge.
The difference between a glass-safe clamp tray and one that isn't usually comes down to two things: padded (rubber or foam) clamp faces that spread pressure instead of pinching a hard edge, and a clamp range that actually matches the desk's measured thickness rather than just 'fits most desks.'
The four picks below are all explicitly built or marketed for glass and other no-drill surfaces, with clamp thickness ranges and padding called out so it's clear which one fits a specific desk before ordering.
