PM Performotor Roof Box Overview
This list covers two hard shell roof cargo boxes from PM Performotor. Both models feature a textured black finish and mount directly to your vehicle's roof rack. The primary difference lies in their internal volume and external dimensions. You can choose between 11 cubic feet or 13 cubic feet of storage space depending on your gear volume.
The 11 cu ft PM Performotor Hard Shell Cargo Box suits drivers needing reliable storage for moderate loads. It measures 53 inches in length and 34 inches in width. The 13 cu ft Lockable Roof Box offers extra capacity for those prioritizing security. It includes a lockable mechanism and measures 56.3 inches long. Both boxes are designed for cars and provide durable, weather-resistant protection for your belongings.
Who PM Performotor Boxes Suit
This range suits drivers needing moderate storage for bulky gear. The smallest model offers 11 cubic feet with a 53-inch length. The larger option provides 13 cubic feet and measures 56.3 inches long. Both use hard shell construction for weather resistance. You get dual-access loading on the larger lockable model. Neither box includes soft-sided flexibility or extreme capacity. If you require ultra-low profiles or massive volumes beyond 13 cubic feet, this brand’s current lineup does not offer those specific features. These boxes fit cars needing reliable, secure roof storage without excessive size.
How to choose the right PM Performotor roof box
-
Compare shell construction types
Both options in this guide use hard shell construction. This design offers better durability and weather resistance than soft fabric alternatives. You get a rigid structure that protects your gear from rain and debris. The textured black finish on both models adds a layer of protection against scratches and UV damage. Hard shells also tend to be quieter on the highway than soft bags. You should choose this type if you prioritize long-term durability and secure storage for your outdoor equipment.
-
Match capacity to your gear
The two models offer 11 and 13 cubic feet of space. You need to estimate the volume of your bulky items. The 11 cubic foot model fits moderate loads and is ideal for weekend trips. The 13 cubic foot version provides extra room for larger gear or longer excursions. Consider the shape of your items as well. A larger capacity does not always mean better usability if the dimensions do not fit your specific items. Measure your gear before deciding on the volume.
-
Check external dimensions for fit
External size affects aerodynamics and garage clearance. The 11 cubic foot model measures 53 inches long and 34 inches wide. The 13 cubic foot version is 56.3 inches long and 36.8 inches wide. You must ensure these lengths fit on your roof rack without overhanging too much. Also, consider the height. The taller 13 cubic foot model may affect clearance in tight parking garages. Measure your vehicle's roof width and length to ensure a safe fit before purchasing.
-
Assess security needs
Security is a key factor for roof boxes. The 13 cubic foot model is explicitly listed as lockable. This feature allows you to secure the lid to the base, preventing unauthorized access to your gear. The 11 cubic foot model does not have a lockable badge in the data. If you store expensive items, the lockable option is safer. You should verify if the lock mechanism integrates with your crossbars. Secure storage ensures your belongings remain safe during travel and when parked.
-
Verify vehicle roof compatibility
Both boxes are designed for roof mounting on cars. You need a compatible roof rack system to install these units. Ensure your vehicle has crossbars or a factory rack that can support the weight. The mount type is specified as roof mount for both models. Check the weight capacity of your existing rack. These hard shell boxes add significant weight. Proper installation is crucial for safety. You must follow the manufacturer's instructions to attach the mounting clamps securely to your bars.
