Check before you buy

Mounting dimension match. Center-to-center hole spacing and thread size (inch vs metric) must exactly match the existing holes or your drawing. A near-miss means redrilling the panel or using a handle that binds.
Mounting direction. Decide whether you need front-mount (screws through the face) or rear-mount (tapped handle legs, screws from behind). Rear-mount hides fasteners but needs access behind the panel.
Material for environment. Use stainless steel (316 for washdown or marine use) or glass-filled nylon where corrosion is a concern, not plated zinc. Plating on die-cast zinc flakes and corrodes in wet or chemical environments.
Grip clearance. Check that the inside clearance fits a gloved hand if operators wear gloves. Low-profile pulls look neat but are unusable with work gloves.

Questions

What is the difference between front-mount and rear-mount pulls?

Front-mount pulls fasten with screws through the handle face. Rear-mount pulls have tapped legs and screw in from behind the panel, which hides the fasteners.
