This product page focuses on the Vilma PTD60S installation box for plasterboard, which is compared with similar VILMA brand models including PTD60, PTD40S, PTD40, GKD60S, and GKD40S. All of these products share the same core material (black or yellow halogen-free polypropylene), concealed mounting method, and basic functionality for electrical installation work. The main differences lie in their dimensions (depth and width), dust and moisture protection ratings (IP20 or IP30), and color, which directly impact available wiring space and installation conditions.
⚙️ The table below compares the key characteristics of the models—such as material type, dimensions, IP protection rating, color, and structural features—to clearly show the practical differences in their application.
| Parameter | Vilma PTD60S | Vilma PTD60 | Vilma PTD40S | Vilma PTD40 | Vilma GKD60S | Vilma GKD40S | Practical significance |
|---|
| Product type | Installation box | Installation box | Installation box | Installation box | Installation box | Installation box | All items are designed for concealed mounting in drywall or plasterboard. |
| Material | Polypropylene (halogen-free) | Polypropylene (halogen-free) | Polypropylene (halogen-free) | Polypropylene (halogen-free) | Polypropylene (halogen-free) | Polypropylene (halogen-free) | All options are eco-friendly, safe, and do not emit toxic halogen compounds when exposed to heat. |
| Dimensions (W x D x H) | 7 x 7.5 x 6.2 cm | 7 x 7 x 6.2 cm | 7 x 7.5 x 4.7 cm | 7 x 7 x 4.7 cm | 7 x 7.5 x 6.2 cm | 7 x 7.5 x 4.2 cm | Models with greater depth (6.2 cm) and width (7.5 cm) provide more internal space for wire routing compared to compact versions (4.2–4.7 cm depth). |
| Protection rating | IP20 | IP20 | IP20 | IP20 | IP30 | IP30 | GKD series models feature enhanced IP30 protection compared to the standard IP20 level of the PTD series. |
| Color | Black | Black | Black | Black | Yellow | Yellow | Color does not affect technical specs but helps visually distinguish series (such as yellow for GKD items). |
◎ The table below evaluates usage scenarios to help determine which specific box best suits your installation needs.
| Use case | Recommended product | Why |
|---|
| Installation in drywall with complex wiring and multiple connections | Vilma PTD60S or Vilma GKD60S | The increased depth of 6.2 cm and width of 7.5 cm provide ample internal space for comfortable arrangement of wire bundles and connectors. |
| Installation in thin partitions with limited cavity depth | Vilma PTD40 or Vilma GKD40S | The shallower depth (4.2–4.7 cm) allows installation in narrow wall cavities where standard deep boxes will not fit. |
| Projects requiring a higher ingress protection rating | Vilma GKD60S or Vilma GKD40S | Provide an IP30 protection class, exceeding the basic IP20 rating found in the other reviewed options. |
The Vilma PTD60S installation box differs from several alternatives by offering an increased depth and width (7x7.5x6.2 cm), making it the optimal choice for standard drywall installations where extra space is needed for routing cables. If a higher IP30 protection rating is required, the alternative Vilma GKD60S provides identical dimensions with better protection, while narrower partitions will benefit more from shallower versions like PTD40, PTD40S, or GKD40S.
