Replacement Knob Caps for Motorola XPR3300/3500

This set provides two volume knobs and two channel selector knobs designed for Motorola XPR3300, XPR3500, DEP550, DEP570, DP2400 and MTP3150 series radios. It serves technicians and operators who need to restore tactile control on worn or damaged handsets.

Secure Fit During Extended Use

The caps mount quickly and hold firmly on the radio shafts, resisting vibration and repeated adjustment throughout long shifts. They maintain their grip without loosening, so volume and channel changes stay precise even after months of daily handling.

Durable Construction for Field Conditions

Moulded from robust plastic, the knobs withstand drops, moisture and temperature swings common in marine and industrial environments. The package includes two pairs, giving a spare set for immediate swap-out when a cap cracks or goes missing.

Questions about this item

Do these knob caps generate any noise, heat or extra power draw when the radio runs all day?

No. They are passive plastic caps that simply fit over the existing volume and channel shafts, so they add no electrical load, no heat and no sound.

What must I already own for these caps to work?

You need a compatible Motorola radio — models XPR3300, XPR3300E, XPR3500, XPR3500E, DEP550, DEP550E, DEP570, DEP570E, MTP3150, XIR P6600, P6600I, P6620, P6620I or DP2400 — with the original volume and channel knobs in place.

Will they fit alongside the older XPR3000 or DP2400 units I still use?

Yes. The caps are listed as compatible with the DP2400 and the XPR3000 series, so they install directly on those legacy radios without modification.
