Bessey PS130 seaming clamp is an extra large solid surface seam vac clamp designed for pulling and leveling seams on smooth, non-porous materials. Twin vacuum cups secure the PS130 to granite, marble, corian, plastic or glass, so the clamp grips directly to finished surfaces during joining work. A steel spindle then smoothly draws the seams together with controlled force, which helps pull tight joints across longer runs. Guide rails form a solid, rigid frame that supports the vacuum cups, keeping both sides of the joint aligned as pressure is applied. Leveling toggles act directly on the work surface to ensure a smooth surface joint, which reduces grinding, sanding and finishing time after the adhesive cures. This combination of vacuum hold-down, guided clamping and on-board leveling gives installers a single tool focused on seam straightening and flushness.
The solid surface seam vacuum clamp XL uses its twin vacuum cups to attach directly to the solid surface, so setup centers on placing the cups on clean, smooth areas flanking the joint. Once positioned, the vacuum operating button activates and locks the cups to the work surface, holding the PS130 in its working location. The steel spindle is then turned to draw the two sides of the seam together, using the guide rails as a rigid path for even pressure. As the seam closes, the leveling toggles are adjusted to bring both surfaces into the same plane, using the rigid frame as a reference. This sequence lets installers pull, align and level seams in a single setup focused along the joint.
The SAP description identifies this tool as a solid surface seam vac clamp XL, indicating an extra large format aimed at solid surface seams. Twin vacuum cups secure the clamp to smooth, non-porous materials such as granite, marble, corian, plastic or glass, so it is suited to countertop runs, backsplashes or similar flat panels made from those materials. Because the vacuum cups rely on smooth, non-porous surfaces, the clamp operates directly on finished tops rather than on underlying structure, which focuses force where the seam actually meets. The rigid guide rails support both vacuum cups as a single frame, so the clamp spans across the joint and helps keep both sides tracking together when the spindle is tightened. In practice, this means long, straight seams in solid surface or stone can be pulled together and held while adhesive sets, using the PS130 as the core alignment tool.
The Bessey Tools PS130 uses a steel spindle to smoothly draw the seams together with just the right pressure, so closing force is applied gradually rather than in abrupt steps, which helps maintain straight joints as they tighten. Guide rails create a solid, rigid frame supporting the vacuum cups, and this rigid link keeps the cups from shifting relative to each other, so the two sides of the seam come together along a controlled path. Leveling toggles ensure a smooth surface joint by letting installers fine-tune the height of each side while the clamp is under load, which directly reduces the amount of grinding, sanding and finishing required after the bond cures. The vacuum operating button activates and locks the vacuum seal on the work surface, keeping the clamp stable while these adjustments are made, so alignment work can focus on the seam rather than tool movement. Overall, the solid surface seam vacuum clamp XL layout combines holding, pulling and leveling functions into one operation that supports consistent seam flatness.
The PS130 uses twin vacuum cups to secure to smooth, non-porous materials or solid surfaces such as granite, marble, corian, plastic or glass, so it grips directly to these finished panels during seaming work.
The solid surface seam vacuum clamp XL uses a vacuum operating button that activates and locks the vacuum seal on the work surface, holding the clamp in position while seams are drawn together and leveled.
The Bessey PS130 seaming clamp uses a steel spindle that smoothly draws the seams together with just the right pressure, helping create tight joints while maintaining controlled closing along the guide rails.
The guide rails on the Bessey solid surface clamp create a solid, rigid frame supporting the vacuum cups, so both sides of the seam move together in alignment as the spindle is tightened.
The leveling toggles on this clamp ensure a smooth surface joint across the seam, which reduces grinding, sanding and finishing time needed to bring solid surface or stone sections flush.
The SAP description lists this product as a solid surface seam vac clamp XL, indicating an extra large configuration suited to spanning and pulling wider or longer seams on solid surface or similar panels.
The Bessey Tools PS130 extra large solid surface seam vac clamp combines twin vacuum cups, a steel spindle, guide rails and leveling toggles to address pulling and flattening seams on smooth, non-porous surfaces. Because the vacuum operating button locks the cups directly to granite, marble, corian, plastic or glass, the clamp works where the joint actually sits instead of relying on external clamping points. For installers and fabricators working with these materials, choosing this clamp brings seaming, alignment and leveling into one focused tool that supports clean, low-finish joints on demanding solid surface projects.
