Bottle side-walls much thicker and more ridgid than all other fountain bottles.

Thick side-walls are designed to better resist changes in barometric pressures which causes lesser (thin-walled) bottles to collapse and over-flood dampeners.

Translucent side has calibrated scale for quick and easy measurement of fountain concentrate.

This Kompac fountain bottle also fits the AB Dick fountain bottle cap perfectly, and it's smooth flat top surface creates a secure seal to bottle cap.

Quality does'nt cost, it pays, always buy Genuine Kompac Replacement Parts!
