Bessey PS55 seaming clamp is a standard size clamp designed to draw solid surface seams together on smooth, non-porous materials. The clamp uses twin vacuum cups to secure each PS55 unit to surfaces such as granite, marble, Corian, plastic, or glass, so it can hold firmly while you align a joint. A steel spindle smoothly draws the seams together with controlled pressure, helping you pull two pieces into tight contact without sudden movement. Guide rails create a solid, rigid frame that supports the vacuum cups, so the clamping force stays aligned along the seam instead of twisting. Leveling toggles are built in to help you bring the two surfaces to the same height, which supports smoother joints and reduces grinding, sanding, and finishing time after bonding. Each clamp is rated at 48 lb force, giving a defined clamping force for seaming work.
The PS55 solid surface seam vac clamp relies on twin vacuum cups to mount to smooth, non-porous materials such as granite, marble, Corian, plastic, or glass, so the clamp attaches directly to the work surface instead of to a bench or edge. Once in place, the steel spindle lets you draw the seam together with pressure applied along the guide rails, supporting consistent joint closure. The rigid guide rails connect the vacuum cups, so the seam force transfers along a stable frame rather than through flexible components. Leveling toggles on the clamp allow you to move one surface relative to the other at the joint, so you can correct minor height differences as you close the seam.
The PS55 is described as a solid surface seam vac clamp, so it is suited to joining sheet materials that present smooth, non-porous faces. Twin vacuum cups hold each clamp to granite, marble, Corian, plastic, or glass, so the tool grips directly to finished faces during seaming. Because the PS55 is a standard size seaming clamp, it works well in common countertop and panel seam layouts where there is enough flat area for the vacuum cups and guide rails to span the joint. The 48 lb force rating defines how much pulling capability the clamp provides at the seam, which helps set expectations when drawing tight joints in dense materials during solid surface installation or fabrication tasks.
The PS55 uses guide rails to create a solid, rigid frame that supports the vacuum cups, so seam alignment is maintained as the clamp is tightened. The steel spindle runs within this structure and smoothly draws the seams together, which helps prevent sudden shifts that could misalign the joint. Leveling toggles give a way to adjust the relative height of the two surfaces at the seam, so you can bring them into a smooth, flush plane along the joint line. This alignment support reduces grinding, sanding, and finishing because the surfaces meet more closely in height and position before curing. By combining vacuum mounting, a rigid rail frame, a steel spindle, and leveling toggles, the PS55 is configured to pull, hold, and level solid surface seams in a repeatable way.
The PS55 seaming clamp uses twin vacuum cups to secure to smooth, non-porous materials such as granite, marble, Corian, plastic, or glass, which supports solid surface and similar fabrication work.
The PS55 uses a steel spindle running between guide rails to smoothly draw the seams together with pressure, which helps close gaps while keeping joint movement controlled along the seam.
On the PS55 clamp, the guide rails create a solid, rigid frame supporting the vacuum cups, so seam forces stay aligned and the clamp resists flexing during tightening at the joint.
Leveling toggles on the PS55 help produce a smooth surface joint by letting you adjust relative height at the seam, which reduces follow-up grinding, sanding, and finishing work.
The PS55 seaming clamp is rated at 48 lb force, giving a defined pulling capability at the seam so installers can match the clamp to typical solid surface joint requirements.
The PS55 is described as a solid surface seam vac clamp and standard size seaming clamp, indicating a purpose-built design for joining and leveling seams in smooth, non-porous sheet materials.
The PS55 solid surface seam vac clamp from Bessey Tools combines twin vacuum cups, a steel spindle, guide rails, and leveling toggles to handle seam pulling and leveling on smooth, non-porous materials such as granite, marble, Corian, plastic, or glass. The standard size format and 48 lb force rating give a clear picture of how it fits typical solid surface seaming tasks. For installers and fabricators needing a clamp that mounts directly to finished faces while supporting joint closure and height alignment, this PS55 configuration offers a focused option for seam work on solid surfaces.
